Conduit

Make tight bends in machine and equipment wiring with this conduit. Also known as mechanical protection tubing (MPT), it withstands vibration, is flame retardant, and resists oil, solvents, and UV light. When used with fittings for flexible plastic conduit, it seals out air and liquid.

Straight Adapters

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.

Grommets

Preventing wear and cracks, these grommets shield the sections of your conduit that rub and bang against nearby components. They’re also known as wear rings and abrasion rings. Use them in applications where machinery vibrates, conduit is dragged across a surface, and robots move dynamically. They have a two-piece construction, so you can attach them to any part of the conduit without disrupting your system. To make sure they stay in place without compressing the conduit and damaging the cables inside, they have internal grooves that hug the conduit’s ridges.
