This Nylon Strain Relief (Cable Gland) with 1/2" NPT Thread will provide your application with a product made of exceptional quality.

Modularity: The Strain Relief allows you to increase and decrease the cable opening by just swapping out the standard and reduced inserts.

The self locking ACME thread on the dome and flex top ensures that the overlapping splines apply a concentric seal, thereby preventing the form seal from being pulled out of the fitting & ensuring pull-out protection of your cable without damaging it.

Kinking and chafing of the cable is eliminated with use of the Flex Nut.
