Our quick connection technology provides a simpler, safer, and a more cost-effective solution for connecting Copper, PEX, PE-RT and CPVC piping in plumbing and heating applications. The push fittings and valves can be installed in hot or cold and in wet or dry lines system pressures should be relieved to avoid injury prior to installation, and permit 360 Degrees rotation of the pipe while the system is depressurized.Removal of our push fittings is effortless with our patented Slip Clip release tool. The tube stiffeners included in the package are intended for PEX connections only, and not needed for copper and CPVC applications.
