Plastic Submersible Cord Grips

Able to resist most chemicals and withstand use underwater, these nylon grips are rated IP68 for protection from dusty environments and prolonged submersion. A rubber bushing and O-ring create a tight seal to prevent liquid from entering the connection. All are CE marked and TUV Rheinland certified, which means they meet European safety standards. Grips with UL certifications meet American safety standards, while those with C-UL and CSA certifications meet Canadian safety standards. Some also meet standards for marine vessels classed by DNV-GL.

Grips with metric threads meet IP69 for protection from high-pressure washdowns.

Tighten the screw-down clamp on these grips for superior pull-out resistance while relieving tension at connection points. Grips are rated IP68 for protection from prolonged submersion and IP69K for protection against high-pressure, high-temperature jets of water. A rubber bushing and O-ring create a tight seal to prevent liquid from entering the connection.

Low-Temperature Brass Submersible Cord Grips

Keep cords from coming loose and seal water out of enclosures in extremely cold labs and storage areas. Thanks to their plastic bushing and rubber O-ring, these grips withstand temperatures as low as -75° F. They’re NEMA and IP rated, so you can safely submerse them under water, though only for short periods of time. They also stand up to dust, weather, washdowns, and oil. Nickel plated, they resist corrosion. All of these grips relieve strain on your cord if it’s pulled, prolonging its life.
