The SHARKBITE/CASH ACME 23104CP25 is a 25-pack of 1-inch annealed copper crimp rings designed for making secure connections on PEX SDR-9 pipe. Each ring slides over the PEX pipe and is crimped into place using a standard PEX crimp tool, creating a reliable, leak-resistant joint. Annealed copper provides the ductility needed for consistent deformation during crimping, ensuring a tight, uniform seal. These rings are a standard consumable for residential and light commercial plumbing rough-in, repipe projects, and hydronic distribution systems where PEX tubing is the specified material.
These crimp rings are suited for use in water supply distribution, radiant heating loops, and other PEX-based piping systems where a 1-inch connection is required. The 25-count pack is appropriate for jobs with multiple connections at the same size, reducing the need for multiple trips to the supply house. Plumbers and pipefitters working on new construction or retrofit applications will find the pack quantity practical for typical rough-in work.
Designed for use with 1-inch PEX SDR-9 pipe. Intended for use with standard PEX copper crimp tools that conform to ASTM F1807 tooling specifications.
Installation is performed by licensed plumbers following applicable codes such as the IPC or UPC. Shut off the water supply and depressurize the line before cutting into any existing pipe. Slide the crimp ring onto the PEX pipe before inserting the fitting, then position the ring per the fitting manufacturer's minimum insertion depth requirement and crimp with a calibrated PEX crimp tool. Inspect each completed crimp with a go/no-go gauge to verify a properly formed connection before concealing the work.
