Eff eff123-03-lf 1/2 X 1/2 Pex X 3/8 Od Mini Tee Ball Valve Lead-free

Product Description

The EFF eff123-03-lf is a lead-free mini tee ball valve from Eastern Foundry and Fitting, designed for residential and light commercial plumbing applications where reliable flow control is required in tight spaces. This valve belongs to the EFF123 Series and features a 1/2 x 1/2 x 3/8 inch nominal configuration with PEX x PEX x OD compression connections. It is well suited for plumbers, mechanical contractors, and trade professionals working with PEX tubing systems in potable water, radiant heating, and hydronic distribution lines. The body is constructed from brass meeting ASTM B124 C46400 standards, offering strong corrosion resistance and long service life in demanding conditions. The valve seat is made from PTFE, the stem from brass, and the sealing components use EPDM material, all of which contribute to consistent, leak-free performance over repeated cycles. The ball itself is brass, and the handle is a zinc alloy quarter-turn style that allows fast, easy shutoff with a single 90-degree rotation. With a pressure rating of 400 psi and a maximum temperature rating of 250 degrees Fahrenheit, this valve handles the demands of hot and cold water distribution systems. The inlet to outlet length measures 2.008 inches and the overall height is 1.89 inches, making it a compact solution for space-constrained installations. The lead-free construction ensures compliance with safe drinking water regulations, making it appropriate for potable water applications. The double O-ring seal on the stem provides added protection against leaks at the stem connection, while the dezincification and stress corrosion-resistant materials extend the life of the valve in challenging water quality environments. This mini tee ball valve is a practical, code-compliant choice for PEX-based plumbing rough-in and service work.

• Lead-free brass body meets ASTM 1807 and ASTM B124 C46400 standards for safe potable water use
• Quarter-turn operation with zinc alloy handle allows fast shutoff in tight spaces
• Double O-ring seal stem and EPDM seals provide reliable, long-term leak protection
