Eff 102666-lf Brass Elbow Fitting 3/4 Inches Pex X 3/4 Inches Male Sweat

Product Description

The EFF 102666-lf is a brass elbow fitting designed for plumbing applications that require a directional change in the pipe run. It connects a 3/4 inch PEX tubing side to a 3/4 inch male sweat copper connection. This makes it a transition fitting, bridging PEX flexible tubing systems and traditional copper pipe systems in a single fitting. Plumbers and mechanical contractors use this type of fitting when roughing in residential or light commercial water supply lines. It is also common in retrofit work where a contractor is updating an older copper system with new PEX runs. The elbow angle allows the pipe to change direction without cutting and soldering multiple pieces of copper, saving time on the job. The brass construction is a key feature of this fitting. Brass is a durable, corrosion-resistant alloy well suited for potable water systems. It handles the pressures and temperatures found in standard domestic water supply lines. Brass fittings are compatible with both hot and cold water service, making them a go-to choice for residential plumbing. The male sweat end requires standard soldering with flux and solder to join to a copper female socket or fitting. The PEX end is designed to accept a 3/4 inch PEX insert connection, which works with standard crimp rings, clamp rings, or expansion-style PEX tools depending on the system in use. This fitting is lead-free, as indicated by the LF designation in the part number, meeting NSF and ANSI standards for safe use in potable water plumbing. Lead-free brass fittings are required by code in most jurisdictions for drinking water systems. Plumbers working on jobs that require code compliance for lead content should verify this designation when sourcing fittings. The 102666-lf is a practical, code-compliant transition fitting for PEX-to-copper changeovers in water supply rough-in and retrofit work.

• 3/4 inches PEX connection on one end and 3/4 inches male sweat copper connection on the other end
• Lead-free brass construction meets NSF and ANSI standards for potable water applications
• Elbow fitting design allows directional change in pipe runs, reducing the need for additional couplings

Product Highlights

The EFF 102666-lf delivers a reliable, lead-free brass transition between PEX tubing and copper sweat connections in a 3/4 inch elbow configuration. It is built for residential and light commercial potable water plumbing where code-compliant materials and a clean directional transition are required.
