Adapters for Flexible Plastic Conduit

Tabs on one end snap into grooves in conduit; the other end attaches to a knockout in an outlet box or enclosure. These adapters help seal out air and liquid when used with flexible plastic conduit. All meet IP68 for prolonged submersion and IP69K for high-pressure, high-temperature washdowns. They withstand vibration, are flame retardant, and resist oil, solvents, and UV light.

Fittings for Shielded Flexible Plastic Conduit

Made of brass, these adapters provide electromagnetic interference (EMI) protection when connecting shielded flexible plastic conduit to a knockout in an outlet box or enclosure. Twist the compression end over the conduit; tighten the compression ring to secure.

A brass locknut is required (not included) when installing in an unthreaded knockout.
