About Conduit

Harsh Environment Liquid-Tight Flexible Metal Conduit

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

Conduit

The toughest liquid-tight flexible metal conduit we offer, this resists oil, chemicals, and extreme temperature fluctuations. It also seals out liquid when used with liquid-tight fittings. The steel core provides crush resistance, and the cover is UV light resistant. Use this bendable conduit for connections to motors and other equipment in tight areas.

Adapter with Wire-Mesh Grip and Locknut

Adapter

When used to connect liquid-tight flexible metal conduit to a knockout in an outlet box or enclosure, these fittings seal out liquids. Attach the twist-in end to conduit with a few quick turns.

316 stainless steel adapters are corrosion resistant.

Adapters with grounding lug ground conduit outside an outlet box or enclosure. Run a ground wire through the lug. Adapters with a wire-mesh grip provide strain relief and added protection against conduit pullout.

Low-Smoke Flame-Retardant Heat-Shrink Tubing

Material: Polyolefin Plastic
Shrink Ratio: 3:1
Dielectric Strength: 250 V/mil
Shrink Temperature: 250° F
Temperature Range: -65° to 230° F
Specifications Met: MIL-C-24643

Also known as halogen-free tubing, this tubing meets MIL-C-24643 for minimal emission of smoke and gas if exposed to an open flame, so it can be used in enclosed areas such as ships and tunnels. It also has a flame-retardant additive that makes it combustion resistant and minimizes the spread of flames.

Dielectric strength is the maximum voltage a material can handle before it starts to breakdown.
