Eff eff123-02-lf Mini Ball Valve 1/2 Pex X 1/2 Pex X 1/4 Od Compression Tee Lead-free

Product Description

The EFF eff123-02-lf is a lead-free mini ball valve from Eastern Foundry and Fitting, part of the EFF123 Series. It is designed for use in plumbing systems where PEX tubing meets OD compression fittings. The valve features a tee configuration with a 1/2 inch PEX inlet, a 1/2 inch PEX outlet, and a 1/4 inch OD compression branch connection. This makes it a practical choice for residential and light commercial water distribution systems, radiant heating lines, and any application where a compact shutoff or flow-control valve is needed at a branch point. The body is constructed from brass that meets ASTM B124 C46400 standards, giving it strong resistance to corrosion and mechanical stress. The seat material is PTFE, which provides a reliable, low-friction seal across a wide range of water temperatures. The stem is brass with a double O-ring seal design that prevents leakage under pressure. The handle is made from zinc alloy and operates with a simple quarter-turn motion, allowing fast shutoff or full flow with minimal effort. An EPDM seal adds further protection against leaks. The valve is rated for up to 400 psi and can handle temperatures up to 250 degrees Fahrenheit. The inlet to outlet length measures 1.969 inches, and the height is 1.89 inches, making this a compact unit that fits in tight spaces. The lead-free construction meets modern plumbing code requirements for potable water systems. Plumbers, pipefitters, and HVAC technicians will find this valve useful for zoning, balancing, and isolation tasks in PEX-based hydronic and domestic water systems. It complies with ASTM 1807 material standards and is suited for both new construction and retrofit work.
