Liquid-Tight Stainless Steel Cord Grips

Prevent liquid from seeping into enclosures in highly corrosive environments. These cord grips are stainless steel, so they resist corrosion from moisture and mild chemicals, such as the ammonia in cleaning solutions. Sealed with an O-ring, they're IP and NEMA rated to keep out dust and water, even during washdowns.

A zinc-plated steel or nickel-plated brass locknut anchors these cord grips in the knockout. For maximum corrosion resistance, replace zinc-plated steel locknuts with stainless steel ones.

Wet-Environment Sealing Grommets

Style A

Two flanges grip the surface to stop splashes and strong jets of water from passing through holes. Use these grommets as plugs or cut a hole in the center to route wire, cable, and cords. IP rated, they also seal out dirt, debris, and other invisible particles as small as .075 mm, so they’re good to use outdoors and in dusty facilities.

Style A

TPE Rubber—These grommets combine the rigidity of plastic for a tight grip with the flexibility of rubber for easy installation.

Continuous-Flex Liquid-Tight Plastic Cord Grips


Straight	90° Elbow

Prolong the life of cords that repeatedly bend, such as those installed in robots, while sealing out moisture where they connect to enclosures. A spiral extension wraps around cords close to the connection point, where most damage occurs, and gently flexes to prevent kinks. Sealed with an O-ring, these cord grips are IP and NEMA rated to block out dust and water, even during washdowns. A locknut anchors them in the knockout.

Continuous-Flex Snap-In Liquid-Tight Plastic Cord Grips

Reduce the time it takes to seal and secure cords that repeatedly bend. These cord grips don't require any fastening—just push them into the knockout and they snap into place. However, they’re not as secure as threaded cord grips. Often used in robotics, they have an extension that wraps around cords close to the connection point, where most damage occurs. The extension flexes gently to prevent sharp bends and kinks, prolonging cord life. IP rated, these cord grips seal out dust and water.
