The RWC 23104CP25 is a 1-inch copper PEX crimp ring sold in a 25-pack, designed for use with barbed PEX fittings in potable water and radiant heating systems. The crimp ring slides over the outside of the PEX pipe and is compressed using a calibrated crimp tool to form a secure, leak-resistant mechanical connection around a barbed fitting. This method meets widely adopted standards for residential and light commercial plumbing and hydronic applications. Plumbers and pipefitters use these rings as a reliable, tool-based alternative to push-to-connect joining methods.
These crimp rings are suited for PEX-a, PEX-b, and PEX-c tubing installations in residential and light commercial plumbing, in-floor radiant heat, and potable water distribution systems. The 25-pack format is practical for jobs requiring multiple connections on a single run or for stocking a service van. Each ring is sized for 1-inch PEX pipe and compatible barbed insert fittings of the same nominal size.
Designed for use with 1-inch barbed PEX insert fittings and 1-inch PEX tubing as an OEM-style crimp connection component in standard residential and light commercial plumbing systems.
Installation requires a calibrated PEX crimp tool sized for 1-inch rings and a go/no-go gauge to verify proper crimp diameter after compression. Shut off the water supply and depressurize the line before cutting pipe or making connections. Work should conform to local plumbing codes and applicable IPC or IRC provisions governing PEX installations. Do not reuse a crimp ring once it has been compressed.
