High-Temperature Plastic Submersible Cord Grips

Made of PVDF, these grips are able to withstand temperatures up to 300° F and are corrosion- and chemical-resistant. Grips are rated NEMA 12 for protection from splashing oil and coolant as well as IP68 and NEMA 6 for protection from continuous submersion. They’re also rated IP69K and NEMA 4X, which means in addition to being submersible, they withstand high-pressure, high-temperature washdowns and can be dunked in corrosive liquids without any affect. A rubber bushing and O-ring create a tight seal to prevent liquid from entering the connection.

Locknut and O-Ring Kit

These cord grips are lightweight yet durable. As you tighten the grip, a nylon inner ring and lubricated rubber bushing secure your cable, prevent overtightening, and create a seal around the cord to block out liquid. The inner rings are colored by size so you can identify them at a glance.

Locknut and O-ring kits (sold separately) create liquid-tight seals between cord grips and enclosure knockouts. Rated NEMA 4X, NEMA 13, and IP66, the resulting seals provide indoor and outdoor protection against dust, corrosion, water projected from a hose, and oil/coolant spray. Each kit includes two locknuts and two O-rings—enough to seal two cord grips.
