Without doubt the easiest way to fit a good, solid, brass fitting into almost any half inch system. Copper, PEX, PE-RT and CPVC will all connect quickly and efficiently forming a lasting joint. But wait! I got it wrong!! No problem, the Slip Clip release tool efficiently disconnects the misplaced fitting or pipe and allows me to try again ... And again ... And again. As many times as I need to really. These quality fittings are also backed by a 7-year warranty. Find on the Home Depot website by searching for this unique reference number, 323409727.
