Continuous-Flex Liquid-Tight Plastic Conduit

For technical drawings and 3-D models, click on a part number.

Conduit

Also known as Type A, this conduit meets the demands of continuous motion while sealing out liquid when used with liquid-tight fittings. A layer of nylon provides strength during flexing. This conduit is crush and abrasion resistant as well as flame retardant. It also resists oil, chemicals, and UV light.

Straight Adapters

Acetal

Steel

One end twists into a piece of conduit for a quick connection; the other end attaches to a knockout in an outlet box or enclosure. These fittings seal out liquid when used with continuous-flex liquid-tight plastic conduit.

Acetal fittings resist corrosion and chemicals. Steel fittings are stronger than acetal.
