The RWC 23102CP100 is a 1/2 inch copper crimp ring used to secure barbed PEX fittings inside PEX pipe. The ring slides over the exterior of the pipe, and a PEX crimp tool compresses it to form a leak-resistant mechanical connection. This pack contains 100 rings, making it well suited for new construction rough-ins, repipe projects, or any job requiring a high volume of PEX connections. Plumbers and pipefitters working with potable water or hydronic systems rely on this style of connection for its straightforward installation and code-accepted performance.
Copper crimp rings are used with 1/2 inch barbed PEX fittings across residential and light commercial plumbing applications. Common install scenarios include potable water supply lines, in-floor radiant heating loops, and hydronic distribution manifolds. The rings are compatible with standard ASTM F1807 crimp-style PEX connections and are installed using a calibrated PEX crimp tool with a go/no-go gauge for verification. The 100-pack quantity suits production plumbing work where efficiency and consistent inventory matter.
Designed for use with 1/2 inch barbed PEX fittings installed in ASTM F1807 crimp-style PEX plumbing systems.
Installation is performed by a licensed plumber using a calibrated PEX crimp tool sized for 1/2 inch rings. Shut off and depressurize the water supply before making or modifying any connections. After crimping, verify each ring with a go/no-go gauge before pressurizing the system. Follow applicable local plumbing codes and IPC guidelines for PEX installations in potable water systems.
