Eff 103266-lf Brass Pex to Male Sweat Adapter 3/4 in Pex X 3/4 in Male Sweat

Product Description

The EFF 103266-lf is a 3/4 inch PEX to 3/4 inch Male Sweat brass adapter fitting designed for residential and commercial plumbing systems. This adapter connects PEX tubing on one end to a male sweat copper connection on the other. It gives plumbers and contractors a reliable way to transition between PEX and copper piping without extra fittings or adapters. The 103266-lf is built from solid brass, which is known for its durability, corrosion resistance, and long service life in both hot and cold water applications. Brass fittings are a preferred choice in professional plumbing work because they hold up well under pressure and temperature cycles that are common in residential water supply lines and hydronic heating systems. The male sweat end of this fitting is designed to be soldered directly onto copper pipe or a copper female fitting, following standard sweat soldering procedures. The PEX end accepts 3/4 inch PEX tubing using a compatible crimp ring, clamp, or expansion fitting system, depending on the installation method used on the job. This type of adapter is commonly used when connecting new PEX runs to existing copper systems, retrofitting older copper plumbing with PEX, or roughing in supply lines in new construction where a mix of materials is specified. The 3/4 inch size is one of the most common sizes used in main supply lines and branch lines serving multiple fixtures. Plumbers, pipefitters, and remodeling contractors keep this type of fitting on hand for everyday transitions between PEX and copper. The 103266-lf from EFF is a straightforward, code-compliant fitting that meets the demands of professional trade use.
