Sealcon 3/4" NPT Nickel Plated Brass Hazardous Location Multi-hole Cord Grips, Strain Relief Fittings or Cable Glands are used in applications that need excellent performance and fire resistance. It is possible to reach the NEMA 6 (IP 68) submersible rating, provided that there is an ideal fit. To create an ideal fit, the cable cannot be less than 80% of the diameter of the hole. There also cannot be more than .04" (1 mm) of difference between the diameter of the cable and the diameter of the hole.
The thread on the CD21N7MX dome top is self locking and makes sure that the overlapping splines apply an even seal. This keeps the form seal from being pulled out of the fitting & provides pull-out protection for your cable so it does not cause damage. Hazardous location fittings are ATEX approved, meaning they are useful for potentially explosive environments. This cord grip is designated Ex-e, indicating increased safety. Not recommended for use with armored cable.
