About Conduit

Adapters for Liquid-Tight Flexible Plastic Conduit

Use these adapters to attach liquid-tight flexible plastic conduit to a knockout in an outlet box or enclosure. They provide a connection that seals out liquid and resists oil, corrosion, and UV light. They are UL listed when used with abrasion-resistant liquid-tight flexible plastic conduit (Type B).

Adapters with a push-in end are removable and reusable. The twist-in end attaches to conduit with a few quick turns.

Adjustable-angle elbow adapters can be positioned at any angle from 0° to 90°.
