How does Polycore protect the coupling from corrosion?
The thermoplastic liner on the end of the tubing is a slightly larger diameter than the pin end. When the coupling is screwed on to the tubing, the coupling threads cut into the thermoplastic liner and create a barrier. Any exposed coupling in the J-Area is protected by an internal thermosetting Fusion Bonded Epoxy Coating. Rings, donuts, or premium connections are never required in most conventional applications. Polycore’s technology provides 100% holiday free coverage along the entire string of tubing.
