Cable Glands: Reliable Protection for Cables and Machines
What a cable gland provides
Cable glands securely and tightly connect cables with housings, control cabinets, or machines. They fix cables in the housing, provide tension relief, and protect the interior from moisture and dust. Split cable glands simplify installation for pre-assembled cables. They are able to reopen then reseal the housing without the need to disassemble the cable ends.

Industrial and technical applications
In mechanical engineering, cable glands must be easy to maintain and able to withstand high mechanical loads. The food and beverage and medical technology industries require stainless-steel cable glands to comply with strict hygiene requirements. Corrosion-resistant variations resist the effects of aggressive saltwater environments in shipbuilding and in offshore systems. The automotive industry requires glands that withstand vibrations, temperature fluctuations, and oil, while the railway industry values fire protection according to EN 45545 and vibration resistance according to DIN EN 61373. Chemical-resistant materials are highly valued in the process industry where special glands are required for explosive hazardous environments and that are compliant with Directive 2013/34/EU (ATEX) guidelines. Energy engineering requires durable models for wind turbines and solar power installations.
The right material for your application
-
HELUTOP HT is suited for standard applications in dry, interior spaces.
-
HELUTOP HT-MS cable glands fulfil the requirements of EMC glands.
-
HELUTOP Easy cable glands withstand temperatures up to 100°C.
Plastic (polyamide) cable glands, such as the HELUTOP HT or the HELUTOP Easy, are suited for standard applications in dry, interior spaces. This material has good mechanical characteristics, a low weight, provides electrical insulation, and withstands temperatures up to 100°C. For chemically aggressive environments, we recommend glands made of fibre-glass-reinforced plastics.
Brass cable glands, such as the HELUTOP HT-MS, combine mechanical strength with electrical conductivity. They provide an earthing connection and fulfil the requirements of EMC glands. Our brass glands are available in metric sizes from M12 to M63 with PG or NTP threads and withstand high temperatures.
Stainless-steel conduit glands and other cable glands, such as the HELUTOP HT-E, provide excellent corrosion resistance. The material is suited for aggressive chemicals, extreme temperatures, and maritime environments. The HELUTOP HT-Clean meets the strict requirements of the food and beverage industry, is EHEDG-certified, and FDA-compliant.
EMC protection and special variations
EMC cable glands screen electrical cables against electromagnetic interference. These screen-terminating cable glands create full contact between the screening and housing of a cable. They reliably dissipate interference signals using the 360° screen termination principle. In automation technology and variable-speed drives, EMC cable glands are indispensable.
Flat cable glands are designed for flat cables and ribbon cables that do not securely fit into conventional cable glands, and reliably seal the entry point, even with non-round cross-sections.
Ex glands, such as the HELUTOP HT-PA-EX for explosive hazardous areas, fulfil all ATEX requirements. They prevent sparks or hot surfaces from escaping from inside the enclosure and are tested against IEC 60079, thus guaranteeing their suitability for Zones 1, 2, 21, and 22.

Technical standards and norms
Cable glands fulfil different standards: EN 50262 establishes requirements for metric glands, and EN 62444 defines those for EMC characteristics. The protection class according to IEC 60529 defines how well the gland seals against contact, foreign bodies, and water. IP68 guarantees dust-tightness and resistance to consistent submersion. IP69K additionally enables high-pressure cleaning at high temperatures.
In addition to metric threads (e.g., M12/M16/M20/M25), PG threads (panzer pipe thread) and NPT threads (National Pipe Thread = tapered pipe thread) are also available. And thanks to their UL certification, they are also suited for use in North America. Marine approvals from DNV (Det Norske Veritas) certify sea-water resistance for shipbuilding.

FAQ
A cable gland actively provides tension relief and seals the cable. A cable entry is simply a hole without any screw mechanism.
Measure the outer diameter including the sheath using a vernier caliper. The gland must have a clamping range that encompasses this diameter.
PG is an older, German system. Metric threads (M12, M16, M20) follow international ISO standards and are available globally.
