Eff eff121-08-lf 1/2 Pex X 1/4 Inch Od Straight Lead-free Mini Ball Valve

Product Description

The EFF eff121-08-lf is a straight mini ball valve from Eastern Foundry and Fitting, built for residential and light commercial plumbing systems where space is limited and reliable shutoff is critical. This valve is part of the EFF121 Series and connects a 1/2 inch PEX line to a 1/4 inch OD compression fitting. It is designed for plumbers, mechanical contractors, and service technicians who need a compact, lead-free shutoff solution in tight spaces such as under-sink installations, ice maker lines, and refrigerator water supply connections. The quarter-turn operation allows for fast, easy shutoff with a single 90-degree handle turn. The valve body is constructed from brass that meets ASTM B124 C46400 standards, providing strong resistance to dezincification and stress corrosion. This makes it a durable choice for potable water systems where water chemistry can vary. The seat is made from PTFE, which provides a low-friction, chemical-resistant sealing surface that holds up well under repeated cycling. The stem uses a double O-ring EPDM seal to prevent leaks at the packing area, even after years of use. The ball is brass, and the handle is zinc alloy for a lightweight feel that is easy to operate by hand. This valve is rated for 400 psi working pressure and can handle temperatures up to 250 degrees Fahrenheit, making it suitable for hot water supply lines. The inlet to outlet length is 1.89 inches, and the height measures 1.496 inches, keeping the installed footprint very small. The lead-free construction complies with safe drinking water requirements, making it appropriate for potable water applications across residential and commercial projects. Trade professionals can rely on this valve for ice maker shutoffs, appliance supply lines, water filtration systems, and similar low-flow fixture connections.
