Caps cover the end of pipes, stopping fluid flow and protecting pipe threads. Wolv-Bite push connect fittings are the quickest fittings to use when connecting pipe together. Simply push the fittings onto the pipe and you are done. The advanced grip ring technology and the O-ring seal, provides a push perfect seal, ensuring the fitting does not leak. Wolv-Bit fittings are also designed to be removed using a disconnect clip so future repairs or piping can be completed.
