Sharkbite/cash Acme UA134A5 Pex-a Expansion Coupling 3/4 in 5-pack

Product Description

The SHARKBITE/CASH ACME UA134A5 is a PEX-A plastic expansion coupling designed to connect 3/4-inch PEX-A pipe to a 3/4-inch male NPT fitting. Sold as a 5-pack, this coupling uses the PEX expansion method, which requires a compatible PEX expansion tool and expansion rings to complete the joint. As the pipe returns to its original diameter after expansion, the connection compresses and strengthens over time. Plumbers and pipefitters use this fitting in potable water systems, service lines, and applications requiring burial, including encasement in concrete. It is compatible with PEX-A pipe only and is not rated for PEX-B or PEX-C.

The UA134A5 is suited for residential and light commercial plumbing installations where PEX-A distribution systems terminate at threaded fixtures, valves, or manifold connections. Its approval for burial and concrete encasement makes it a practical choice for underground water service line work. The 5-pack format supports multi-connection jobs or service truck stocking. Because this fitting requires the expansion method, it is intended for use by plumbers equipped with the proper PEX-A expansion tooling.

Key Features

• PEX-A expansion connection grows stronger over time as pipe memory returns the joint to original diameter
• 3/4-inch PEX-A inlet to 3/4-inch MNPT outlet for direct threaded termination

Compatibility

Compatible with PEX-A pipe only. Requires a PEX expansion tool and expansion rings to make the connection. Approved for water service lines and burial applications including concrete.

Installation Notes

Installation is performed by licensed plumbers familiar with PEX-A expansion tooling and applicable plumbing codes such as the IPC. Shut off water supply and depressurize the line before cutting or fitting any pipe. Use the correct PEX-A expansion tool and appropriately sized expansion rings — do not attempt to install this fitting using push-to-connect or crimp methods. Verify local code approval for burial depth and concrete encasement requirements before use in underground service line applications.
