Description ECGJH and ECLK Series Flexible Couplings The ECGJH and ECLK Series are heavy-duty flexible couplings designed for use in hazardous locations where a flexible member is required in a conduit system. These couplings are essential for accomplishing difficult bends, allowing for equipment movement or vibration, and navigating tight spaces where rigid conduit is difficult to install. Engineered for maximum durability in the field, these couplings feature a rugged design capable of withstanding internal explosive pressure (Class 1) and mechanical abuse. Smaller sizes (1/2″ to 2″) utilize a flexible brass inner core with a bronze braid covering and an insulating wire duct liner to prevent grounds, while larger sizes (2-1/2″ to 4″) feature high-strength stainless steel construction.

No, bonding jumpers are not required because the metallic braid provides a continuous electrical path. What is the difference between ECGJH and ECLK? ECGJH has two male threaded end fittings, while ECLK has one female union and one male threaded end fitting. Can these be used in corrosive areas? Yes, for severely corrosive locations, you can order the S758 option, which adds a flexible PVC protective coating What is the maximum length available? Special coupling lengths are available up to 144 inches
