End Caps for Insulated PEX designed for underground burial (PEX or PAP). This product meets specifications for use in ALL outdoor wood boiler applications and installations.

End caps prevent water from entering the underground pipe. If water fills the underground pipe, it will suck heat away from your system and transfer it into the earth, which is capable of absorbing an infinite amount of heat!
