Installation instructions
The rings will harden at low temperatures. To make them soft, keep them at a temperature of
20 °C for 24 hours prior to installation. Before fixing them onto the cable gland, bend the rings to
ensure they are soft and flexible.
1. Check that a suitable cable is being used (i.e., check the mechanical resilience, temperature
range, creep resistance, resistance to chemicals, outer diameter, etc.).
2. Strip the cable in accordance with the table information.
3. Check the outer sleeve for damage and soiling.
4. Insert the cable in the cable gland.
5. Tighten the cable gland until the cable is firmly enclosed by the sealing ring. Do not tighten
the cable gland any more than 1.5 times the specified torques!
