CopperLoc Lead Free Fittings provide hassle-free plumbing and secure connections with minimal labor. They create a permanent connection if needed, however you’ll also have the peace of mind knowing that you may remove the fitting in the future if you need to re-arrange your plumbing. If you’re using PEX you’ll simply need to add a Hi-Flo stiffener, which helps ensure proper seating for the connection. Some of the other push connect fittings that are on the market require the PEX insert to be removed before installation. With CopperLoc, you don’t have to worry about removing the PEX insert before installation because we do not pre-install them.
