Eff 109644-lf 3/4 X 1/2 X 1/2 Pex No Lead Brass Reducing Tee

Product Description

The EFF 109644-lf is a no lead brass reducing tee fitting designed for PEX tubing systems in residential and commercial plumbing applications. Made by Eastern Foundry and Fitting, this tee connects three PEX lines in a reducing configuration: a 3/4 inch run on the main inlet and two 1/2 inch outlets. This makes it ideal for branching a main supply line into smaller distribution lines throughout a building. Plumbers and pipefitters use this type of fitting when they need to reduce flow from a larger trunk line to smaller branch lines serving individual fixtures such as sinks, toilets, or appliances. The all-brass construction ensures long-term durability and resistance to corrosion, which is critical in potable water systems. The no lead compliance means this fitting meets strict federal and state regulations for use in drinking water applications, including the Safe Drinking Water Act requirements for lead-free plumbing products. PEX systems are widely used in modern plumbing because they are flexible, freeze-resistant, and faster to install than copper or rigid plastic pipe. This fitting uses standard PEX crimp or clamp connections on all three ports, making it compatible with most PEX installation tools and systems. The 109644-lf is a direct replacement for fittings also known as U9644-LF, 5423-015, PXRT3411-NL, and PXRT040303LF, giving installers flexibility when sourcing parts. Whether you are working on a new construction project or a retrofit repair, this reducing tee delivers reliable performance in hot and cold water distribution lines. It is a trusted choice for professional plumbers who need code-compliant, durable fittings that work with today's PEX plumbing systems.
