1/2″ Copper PEX Crimp rings are used with PEX tubing and barbed Crimp fittings (F1807). The ring is compressed on the PEX tubing holding the PEX barbed fitting in place. It makes a permanent 360º water tight seal. After crimping Copper PEX rings, the diameter should be checked with a Go-No-Go Gauge, usually included with the PEX crimp tool. Copper PEX rings are made of nearly 100% copper and are easy to install. The copper PEX rings are made in Canada too.
