This fitting is manufactured by Eastern Foundry and Fitting and is built for professional plumbing applications where a reliable transition between PEX and copper systems is required. Plumbers, mechanical contractors, and HVAC technicians use this type of adapter when integrating PEX supply lines into existing or new copper distribution systems. The 103246-lf is constructed entirely from brass, giving it excellent durability, corrosion resistance, and long service life in both hot and cold water systems. The PEX end accepts standard 1\/2 inch PEX tubing using a compatible crimp or clamp ring tool, while the 3\/4 inch male sweat end is soldered directly onto a copper fitting or valve using standard plumbing torch techniques. Lead free construction means this fitting meets the requirements of the Safe Drinking Water Act and is compliant for use in potable water systems. This makes it a suitable choice for residential and light commercial plumbing installations where lead free materials are required by code. PEX to copper adapter fittings like this one are a staple in retrofit and new construction work. They allow plumbers to easily run flexible PEX lines from manifolds or branch points and tie them into copper shutoff valves, ball valves, or fixture supply connections. The brass construction handles typical residential water pressures with ease. Cross-reference part numbers for this fitting include U3246-LF, 4423-149, PSMA3412-NL, and PXMSA1234.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eConnects 1\/2 inch PEX tubing to 3\/4 inch male sweat copper fittings or valves\u003c\/li\u003e\n\u003cli\u003eLead free brass construction meets Safe Drinking Water Act compliance requirements for potable water systems\u003c\/li\u003e\n\u003cli\u003eCompatible with standard PEX crimp or clamp tools on the PEX end and soldered on the sweat end\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe EFF 103246-lf delivers a code-compliant, durable PEX to copper transition in a compact brass fitting.
