Hi-Tech Controls, Inc. Liquid Tight Nylon Strain Relief Fitting CD40MR-BK-N

This Nylon Strain Relief with M40 x 1.5 Metric 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.
