Eff 102164-lf Elbow 3/4 in Pex X 1/2 in Pex Brass Fitting

Product Description

The EFF 102164-lf is a brass PEX elbow fitting designed for plumbing systems that require a directional change in the supply line. This fitting connects a 3/4 inch PEX pipe on one end to a 1/2 inch PEX pipe on the other, making it a reducing elbow. Plumbers and pipefitters use reducing elbows like this one when transitioning from a main supply line to a branch line. The 3/4 inch side handles the higher-flow trunk line, while the 1/2 inch side feeds individual fixtures such as sinks, toilets, showers, or washing machines. This type of transition is common in both residential and light commercial plumbing rough-in work. The brass construction of the EFF 102164-lf gives it strong resistance to corrosion, pressure, and temperature changes. Brass is a preferred material for PEX fittings because it handles the expansion and contraction of plastic tubing without cracking or leaking. It also meets lead-free plumbing standards, which is required in potable water systems under current building codes in most jurisdictions. The LF designation in the part number stands for lead-free, confirming this fitting is safe for use in drinking water applications. PEX plumbing systems have become the standard for residential water distribution because of their flexibility, freeze resistance, and ease of installation. This brass elbow is compatible with standard PEX crimp or clamp ring installation methods. Professionals working on new construction, remodel projects, or system repairs will find this fitting straightforward to install with common PEX tools. Keep this part stocked for jobs that require reducing tees, branch connections, or fixture rough-ins where a directional change and size reduction are both needed in one fitting.
