Eff 103144-lf 1/2 Inch Pex X Pex No Lead Brass Coupling Fitting

Product Description

The EFF 103144-lf is a 1/2 inch PEX x PEX no lead brass coupling fitting made by Eastern Foundry and Fitting. This fitting connects two sections of 1/2 inch PEX tubing in a straight run. It is built from lead-free brass, making it suitable for potable water systems where no lead compliance is required. Plumbers and pipefitters rely on PEX couplings like this one to repair damaged tubing sections, extend existing PEX lines, or complete rough-in work in residential and light commercial plumbing installations. PEX piping systems have become a standard choice in modern construction and remodel projects because of their flexibility, freeze resistance, and ease of installation. A brass coupling fitting provides a rigid, durable connection point within that flexible system. The 103144-lf uses a standard PEX connection method on both ends, making it compatible with most crimp, clamp, or expansion PEX tools depending on the system type. The lead-free brass construction meets NSF 61 and NSF 372 standards commonly required for drinking water applications in residential, commercial, and municipal plumbing projects. This coupling is a direct in-line fitting with no change in direction, ideal for joining two pieces of 1/2 inch PEX pipe end to end. The compact design fits into tight spaces common in wall cavities, under sinks, and in mechanical rooms. Keeping fittings like the EFF 103144-lf on hand reduces downtime during service calls and new construction rough-ins. This part is also cross-referenced under part numbers U3144-LF, 5423-000, EPCP0012-NL, and PXCP03LF, making it easy to identify across multiple supplier catalogs.
