Being a pioneer in the development of breathable cable glands, WISKA today is an expert for breathable components avoiding condensation.
With the launch of the VentGLAND® in 2007, the world's first cable gland with pressure equalisation, WISKA set new benchmarks. VentGLAND® cable glands and VentPLUG pressure equalisation units are nowadays being used around the world, especially in sectors that are moisture and temperature sensitive such as shipping, and the lighting and solar industries.
WISKA VentGLAND® Cable glands
The VentGLAND® combines pressure equalisation and cable gland in a single unit and features high air flow rates as well as high water protection capacity.
The breathable VentGLAND® cable glands are a part of the tried and tested modular SPRINT system. The VentGLAND® can easily be used to replace standard cable glands due to its identical clamping ranges and compatibility with all cap nuts and ranges of multiple and special sealing inserts. The product portfolio is rounded off with VentGLAND® cable glands with EMC-inserts for protection against electromagnetic interference.
The new VentPLUG Pressure equalisation units by WISKA
The VentPLUG is used when a cable gland with an additional pressure equalisation unit is required to vent the enclosure.
Pressure equalisation units from WISKA are now also available in thread sizes M 20 and M 40, in addition to M 12. Both feature a flat, space-saving design to enable flexible usage. Thanks to an improved membrane, the air flow rate of the new VentPLUG in the sizes M 20 and M 40 has more than doubled. The high air flow version even achieves a 2.5 times higher value.
Product range of WISKA venting products in plastic, brass and stainless steel
WISKA products are build of highest quality and made for most demanding conditions. Our Venting products offer:
The diversity of our products provide venting solutions for a broad range of applications. Thread sizes include M 12 to M 63 with a wide range of materials such as polyamide, brass and stainless steel. Completed by their high protection classes of IP 68 and 69, venting products by WISKA appear to be true multitalents. On top of that, they have application specific membranes with different air flow rates and robust properties such as resistance to UV, salt water and aggressive chemicals.
WISKA offers many years of experience and working with customers to provide solutions that meet any individual requirements. You may also use our venting calculator to compute the optimal application of our pressure equalisation products.

With the Railway Series, WISKA has developed an industry-specific expansion of its proven SPRINT® cable gland system, thereby fully meeting the special needs of the rail industry.
Since June 2013, products and their materials that are used in the railway sector must be tested in accordance with the new fire safety standard EN 45545, in order to meet the same quality standards across Europe. This does not only apply to new vehicles; the components used must also meet these requirements in remedial maintenance of railway vehicles. The RW product range complies with the required standards for European railway outfitters in all respects and for all materials used.
WISKA's RW series is the ideal combination of high-value product quality and multiple modularity, while maintaining compliance with standards. The RW components have been successfully tested for fire resistance in accordance with EN 45545-3:2013-08. Furthermore, the entire series meets the highest requirements of Hazard Level 3 that can be applied to the materials used in the railway industry.
WISKA is one of the first European manufacturers to have successfully tested a complete series of cable glands in the differing materials of polyamide, brass and stainless steel to meet both this standard and hazard level.
With the WHK, WISKA is combining its junction box expertise with the idea of power distribution via installation plug connectors.
The modular unit can be supplied pre-wired, using the sockets from most major manufacturers. Pre-fabricated components for building automation, e. g. lighting systems, make it possible to connect the power supply in seconds. Due to diverse mounting options, the new junction box is perfectly suited for flexible and mobile applications. This all makes the WHK the ideal junction box for electrical installations within commercial building.
Your benefits with our WHK
With the LED multi-purpose luminaire 4000, WISKA has developed the perfect lighting solution for use in the maritime industry and the offshore sector. The innovative luminaire is DNV GL certified and, like all WISKA products, stands for the highest “made in Germany” quality.
Beyond excelling the high requirements of maritime lighting, the LED multi-purpose luminaire 4000 reduces maintenance costs to zero. The reason for that is simple: The luminaire dispenses of a driver, which considerably minimises the risk of failure.
With only reduced components and no additional lighting fixture housing, assembly and installation of the LED multi-purpose luminaire 4000 go straightforward. The lighting system has been tried and tested in thousands of operating hours and provides reliable working light regardless of even roughest conditions.
We are expanding our range of non-metallic luminaires with our new LED Multi-purpose Luminaire 2010. Its lightweight and circular design is particularly suitable for installation in areas where there is not much space, such as hatch coaming areas or passage ways. Whether indoor or outdoor: Material and manufacture ensure the luminaire meets the demands of the rough seas.
With our new Push-In cable gland, we are expanding our extensive range of cable glands with another highlight. Push in, tighten from the outside, done: no thread or opening of the enclosure are necessary.
Mechanical strains, sand and humidity turn unprotected cables into major sources of danger in industry. With non-metallic conduits from WISKA, you can save on expensive downtimes and repairs. WISKA offers you the highest level of quality, robustness and a huge variety of products – for static as well as dynamic areas of application.
Our BraceFITTING is a unique product many engineers have been waiting for: A sophisticated closure system, IP68 as standard and a very comfortable installation of the conduit are only three of the advantages that you will love.
There are situations when normal cable protection is not enough. For example when mechanical forces or natural influences have a high impact on the conduits: Our metallic conduits are designed and engineered to handle the highest of demands under the toughest of conditions.
Our metallic conduits comply with the highest standards so that you can install with the feeling of being safe and having your installations well protected. Therefore all our conduits are halogen-free and self-extinguishing. Even if you have special requirements and e.g. need to install cables within the railway industry (requiring EN 45545), we have the right conduits for you: Just take a look at our locomotive.
With their unique design and highest quality, they have met the most demanding installer requirements for years: The COMBI junction box series is an original in every aspect.
Where space for cable installation is limited but the cable type is strictly defined, that's where our ESKV PLUS comes into action. With a wider clamping range and the same standard gland size as well as the same thread, it is the perfect solution and expands the range for the various areas of application in electrical installations.
Using our cable management expertise, we have again developed a new and unique solution: The MagikNUT®!
The MagikNUT® is a polyamide locknut with a built-in stainless steel clip mechanism for EMC shield connections. The MagikNUT® can be used with plastic cable glands and plastic fittings, offering users a high level of EMC protection, quick installation time and savings in material costs.
Our LED Floodlight 5000 is our newest lighting innovation. It is made of an innovative plastic component in a special housing design and stainless steel casing. A heat conductive system made of plastic that will meet more than your requirements. Our redesign has made the 5000 casing even smarter and assembly-friendly and even leight-weight. All features of its modular design and heat conduction stay the same.
Modern technologies are constantly becoming more demanding and complex. This increases the vulnerability of electronic components to electromagnetic disturbances. To protect against such interactions, we offer you two different approaches to EMC cable glands which ensure effective 360° shielding and durable impermeability for individual uses with IP68 / 69.
New in our range is our EMC locknut: The MagikNUT®. This is a polyamide locknut with an integrated stainless steel clip for EMC shield contact. Find out more about our MagikNUT®.
Our metallic BraceFITTING simplifies installation and reliably protects cables. With the IP67 protection as standard, it meets the highest demands placed on the application. The various colour schemes of the O-ring seals tell the user which conduit is the right one at a glance.
With the MARATHON® we are happy to present to you a cable gland with especially high strain relief. You may benefit from our many years of experience in twin-shot production technology, which our R&D department has now used for a new smart design and function.
The MARATHON® separates the sealing from the strain relief function. The basis for this is a clamping cage that is manufactured using two-component injection moulding. In the lower part a TPE fulfills the sealing function permanent and effectively. Eight rounded claws enable an especially high strain relief according to category B (EN 62444) over almost the entire clamping range.
CLIXX® allows easy cable entry thanks to a membrane while also providing strain relief. CLIXX® can be assembled in seconds: simply clip in the hole, insert cable and done.
The demands placed on cable protection products are justifiably high. Along with protection against external conditions such as the temperature, dirt and impact, handling must remain simple and convenient. A demand that our Brace® system meets with conduits and fitting – metallic and non-metallic.

Despite their small and simple design, cable glands are an important component of electrical installations. They are used in nearly all areas of industry and trade.
They allow strain-relieved, water-protected cables to be connected to systems such as junction boxes, distribution boards and switchboards. Cable glands protect electrical components against mechanical and environmental forces such as dust and moisture by connecting the cables securely to casings.
Cable glands consist of three main parts: the cap nut, sealing insert and fitting. So-called EMC inserts may also be used for WISKA cable glands for electromagnetic compatibility. This eliminates the need for special EMC cable glands. Other cable gland designs include ex-cable glands, which are used in hazardous areas, and special hygienic design cable glands, which are used wherever sanitary conditions are necessary (e.g. in the food industry).
Cable glands typically have metric threads that meet global standards. However, standardised steel conduit threads (PG) can also be used. The corresponding glands are called PG cable glands. Unlike in Europe, the standardised, self-sealing NPT thread (national pipe thread) is widely used in the US market. Depending on the application, threadless cable entries may also be used instead of threaded cable glands.

Electrical installations that are subject to major temperature fluctuations and high moisture require a unique solution. WISKA’s innovative pressure equalisation cable gland VentGLAND® contains a semi-permeable ePTFE membrane, which ensures constant pressure equalisation between the inside and outside of the casing.
VentGLAND® allows the casing to breathe. In this way, pressure equalisation cable glands minimise the hazard of condensation formation.
The VentPLUG is used when a cable gland with an additional pressure equalization unit is required to vent the enclosure.
Pressure equalization units from WISKA are now also available in thread sizes M 20 and M 40, in addition to M 12. Both feature a flat, space-saving design to enable flexible usage. Thanks to an improved membrane, the air flow rate of the new VentPLUG in the sizes M 20 and M 40 has more than doubled. The high air flow version even achieves a 2.5 times higher value.
You may also use our venting calculator to compute the optimal application of our pressure equalization products.
Pressure equalisation cable glands by WISKA reduce the hazard of condensation formation in the casings
As a further unique solution, WISKA also has cable glands with hygienic designs in its range. The stainless steel cable gland HatGLAND guarantees “clean” cable entry. It is ideal for use wherever sanitary conditions are necessary such as in the food, chemical and medical technology industries.
Hygienic design cable glands by WISKA are easy to clean and are used wherever sanitary conditions are necessary
Because of their versatile design, WISKA seals guarantee maximum stability for virtually all cables for a wide variety of applications. The comprehensive WISKA sealing insert range is continually being expanded. It encompasses reduction sealing inserts including special designs for low temperatures, blind sealing inserts, multiple sealing inserts and special sealing inserts for flat cables.
Multiple sealing inserts by WISKA securely fasten cables of various sizes to the cable gland
As an alternative to cable glands, WISKA also has membrane cable entries in its product portfolio. CLIXX® enables simple cable entry with soft components with strain relief. CLIXX® can be installed without a counternut or a tool: simply click and insert the cable. QUIXX®, a dual component cable entry with thread or click insertion, supplements the membrane range. It enables the insertion of multiple special cables and replaces cable glands for standard installations.
The threadless CLIXX cable entries are considerably flatter than conventional threaded cable entries

LED reports the current status for quick check of function, without extra costs in our standard version.
High protection
With an IP66 / 67 approved protection level, every component of the socket is ready to resist tough environmental conditions, even if the bayonet cap has been left off.
The WISKA® VentPLUG pressure compensation unit ensures permanent pressure equalisation between the interior and the exterior and therefore, minimises the risk of condensation water (optional).
Quality materials
To ensure efficient performance, every material that is used in our products is of high quality, tested and approved by relevant authorities.
Electrical installations and moisture do not go well together. They lead to power failures in electrical casings, sensors and electrical devices. The danger of short circuits – and thus electrical breakdowns, shortages and disruption of operation – increases wherever there is water. In order to find a solution to this problem, it is necessary to understand how condensation forms.
How does condensation form?
Pressure, temperature and air moisture are constantly changing. Even electrical installations, which must be secured in sealed casings in order to be protected against moisture, are subject to the formation of condensation. The reason: Whether caused by climate or operational conditions, fast fluctuations in temperatures create a disparity in pressure between the inside and outside of the casing. This happens when there is rain, wave impact or entry to a tunnel. Because of the vacuum inside the casing, moist air from outside is sucked in, i.e. through the casing’s seal. Inside the casing, the moist air condenses and causes corrosion or a short circuit.
By using the breathable cable gland VentGLAND® and/or the pressure equalisation plug VentPLUG, the pressure inside of the casing can be adjusted to the surrounding pressure. The casing’s verified protection class is fully guaranteed.
The ideal solution is pressure equalisation
In the past, expensive, high-maintenance electric heating and ventilation systems were installed in order to prevent condensation from forming in the casing. Drip holes in the casings are a less expensive alternative, albeit at the expense of water-tightness and, thus, a high protection rating. The ideal solution is to eradicate the internal and external pressure disparity which causes the formation of condensation. WISKA was the first to develop and produce a water-tight, yet breathable cable gland for pressure equalisation and ventilation.
Enclosure without pressure equalisation (left) and using VentGLAND® (right) after two years time
Hermetically sealed enclosures are insufficient to protect electrical installations from moisture and contaminants. Fluctuating temperatures and environmental factors, especially during outdoor usage, create pressure inside tightly sealed enclosures. This leads to a build-up of condensation as well as damage to the seal that can result in the penetration of moisture and dirt.
Breathable venting products from WISKA ensure effective pressure equalisation between the interior and exterior. This reduces stress on the seal and maintains the enclosure´s protection classes. Venting products from WISKA therefore help to increase operational safety and extend the service lives of electrical installations. This has a sustaining positive effect on maintenance costs.
Moisture and dirt are prevented from entering the enclosure. Air molecules are able to penetrate both sides of the membrane.
The high performance ePTFE membrane used in WISKA venting products has billions of breathable pores to enable an effective air exchange between the interior and exterior. The micrometre pores also prevent liquids, dirt and contaminants from passing through the membrane and entering the enclosure.
The membrane is available with different air flow rates. All of them offer all the properties required for the roughest environmental conditions: They are resistant against UV, salt water, oils and grease. Chemicals and aggressive cleaning substances also have no effect on the membrane's structure and performance.
In a municipal district, 2,000 street and outdoor lights with an IP 68 protection classification require maintenance every 3 years. If pressure equalisation components are not used in the lighting enclosures, protection classes and lighting performance are reduced. This results in maintenance being required every 1.75 years.¹
| 2,000 lights | IP 68 protection | IP 5X protection |
| Maintenance interval | 3 years | 1,75 years |
| Maintenance per year | 667 lights | 1.143 lights |
| Maintenance cost per light | 20 Euros | 20 Euros |
| Maintenance cost per year | 13.340 Euros | 22.860 Euros |
Conclusion: Without using venting products additional costs of more than 70 percent may arise due to higher maintenance requirements.

Small and Hot – this is how the new ShotGLAND cable gland series by WISKA presents itself. It has been designed especially for the industrial usage where extremely hot or very cold ambient temperatures prevail. Thanks to its minimal installation height, the ShotGLAND is one of the flattest cable glands on the market. Truly versatile!
In the LT-version the new ShotGLAND comes with an efficient silicone sealing that can be used in temperatures ranging from -60 °C to 180 °C. This makes ShotGLAND the ideal cable gland for high temperature environments like the steel industry or sensor technology as well as applications with lowest temperatures. Both version standard and LT are offered with an EMC insert. Using different sealing elements large range clamping sizes can be realized.
The ShotGLAND cable gland is available in thread sizes from M 8 to M 63 thereby covering a broad application spectrum. By its compact sealing design the minimal installation height ranging from 10 mm (M 8) to 16,5 mm (M 63) is realized along with a protection class of IP 68 with strain relief.
With the development of the ShotGLAND, WISKA has again proved its long-standing competence for application specific cable glands. ShotGLAND is the ideal addition to the existing cable gland series by WISKA like the modular SPRINT system, the breathable venting products, the Hygienic Design series HatGLAND or the railway series.
WISKA offers lids with a wide range of connector combinations, tailor-made pre-installed. Alternatively, you may also insert the preferred connectors into the plug-in locations independently.

EN 45545 cable glands are equally suitable for all railway vehicles, regardless whether they are passenger carriages, freight cars, locomotives or railcars
Since June 2013, products and materials that are used in the railway industry must be tested according to the European fire protection standard DIN EN 45545 in order to fulfil the same quality standards across Europe. This does not just apply to new vehicles; components used to repair railway vehicles must also comply with these standards. The fire protection standard DIN EN 45545 also applies to cable glands that are used in railway transportation technology.
Fire protection standardisation through DIN EN 45545
DIN EN 45545 has unified national fire protection guidelines, such as DIN 5510-2 (Germany), NFF 16-101 to 103 (France) and BS 6853 (Great Britain) to form a European-wide standard. This unifies strict fire protection standards in trains, tunnels and railway stations, because train fires, especially if they occur inside a tunnel, can quickly become a catastrophe. This hazard must be minimised under all circumstances.
The accredited testing laboratories Currenta and MPA, tested the materials used in fire protection cable glands according to DIN EN 45545-2 and the fire resistance of fire protection cable glands according to DIN EN 45545-3
WISKA has developed a railway series for railway transportation technology. It is in compliance with and at times surpasses the quality and safety requirements of the fire protection standard DIN EN 45545. Railway cable glands are an industry-specific extension of the established SPRINT cable gland system. WISKA is one of the first European producers to successfully test a complete cable gland series with brass, polyamide and stainless steel materials according to DIN EN 45545. An EMC version for electromagnetic compatibility completes the range of railway cable glands for railway transportation.
Innovative material for fire protection cable glands by WISKA
EN 45545 cable glands by WISKA ideally combine top product quality and versatile modularity while complying with safety standards. As a part of a comprehensive testing procedure, WISKA tested the fire behaviour of processed and raw materials according to DIN EN 45545-2. WISKA has tested a wide array of materials for interior and exterior use at recognised testing laboratories in order to develop optimal fire protection cable glands. The result: the complete fire protection series fulfils the highest DIN EN 45545-2 hazard level 3 requirements that can be applied to materials used in railway systems.
