The SHARKBITE/CASH ACME UC955A is a 3/4-inch PEX cinch clamp sold in a 10-pack for securing PEX barb fitting connections on cross-link polyethylene (PEX) tubing. Each clamp is installed using a cinch tool and creates a secure, pressure-rated connection. Once crimped, the connection can be immediately pressure-tested to well over 100 psi, allowing the installer to verify each joint without delay. These clamps are a standard choice for plumbers and pipefitters working on residential or light commercial plumbing systems where PEX tubing is used for water distribution.
The UC955A cinch clamps are suited for 3/4-inch PEX tubing installations, including potable water supply lines, radiant heating distribution, and other cross-link polyethylene piping applications. The 10-pack format is practical for service calls or rough-in work where multiple connections are made in a single visit. Compatible cinch tool is True Value item 608-743. These clamps are designed for use with PEX barb fittings on cross-link polyethylene PEX tubing.
Designed for use on 3/4-inch cross-link polyethylene PEX tubing connections with PEX barb fittings. Use with cinch tool True Value item 608-743.
Installation should be performed by a licensed plumber in accordance with local plumbing codes and IPC guidelines. Shut off the water supply and depressurize the line before cutting tubing or disturbing existing connections. Use the correct cinch tool to achieve a proper crimp — an improperly sized or worn tool can result in a failed connection. After crimping, pressure-test each fitting before concealing the installation.
