Sealing ring DR-NBR series

The sealing ring DR-NBR enables the protection rating on conduit fittings MSV, KSV and WSV to be increased from IP 54 to IP 65. To do so, simply insert the sealing ring into the first recess at the end of the cable protection conduit.To guarantee reliable installation, the clamping ring should be unlocked before the conduit is assembled. Following assembly of the cable protection conduit in the conduit fitting, protection rating IP 65 is achieved. The sealing ring can only be used for cable protection conduits with standard corrugation and crush resistance > 400 N/100 mm.
