Eff 103344-lf Brass Adapter 1/2 in Pex X 1/2 in Female Sweat

Product Description

The EFF 103344-lf is a 1/2 inch PEX to 1/2 inch Female Sweat brass adapter fitting designed for residential and commercial plumbing systems. This adapter connects PEX tubing on one end to a female sweat copper connection on the other, making it a reliable transition fitting for mixed-material plumbing installations. Plumbers and contractors use this type of fitting when transitioning between PEX supply lines and copper pipe systems, a common need in remodel work, new construction, and repair jobs. The 103344-lf is manufactured from solid brass, which provides excellent corrosion resistance and long service life in both hot and cold water applications. Brass adapter fittings like this one are a staple in the trade because they hold up well under pressure, resist dezincification in lead-free formulations, and create secure, leak-free connections when properly installed. The PEX end of this adapter is sized at 1/2 inch, matching standard half-inch PEX-A, PEX-B, and PEX-C tubing used throughout residential potable water systems. The female sweat end is also 1/2 inch, designed to receive a 1/2 inch copper pipe that is then soldered in place using standard torch and solder techniques. This fitting is well suited for water distribution lines, branch supply runs, fixture connections, and retrofit projects where PEX is being tied into an existing copper system. The compact brass construction keeps the fitting lightweight without sacrificing strength. Plumbers working on tight rough-in locations will appreciate the straightforward design that allows clean, direct transitions without additional unions or couplings.
