Permasert mechanical couplings are non-corrosive and require no cathodic protection or protective coatings.

The Permasert coupling has a pull-out strength greater than the connected polyethylene tubing. Its one-piece construction and design ensure consistent, gas-tight connections in all weather conditions. Permasert couplings are non-corrosive and molded from industry leading PE4710/Bimodal PE3408 which provides significant performance advantages versus other polyethylene resins.
