Eff 105246-lf Non-swivel Adapter 1/2 in Pex X 3/4 in Fpt Brass

Product Description

The EFF 105246-lf is a brass non-swivel adapter fitting designed to connect 1/2 inch PEX tubing to a 3/4 inch female pipe thread (FPT) fitting. This type of adapter is a core component in residential and commercial plumbing systems where PEX tubing meets threaded pipe connections. Plumbers, pipefitters, and mechanical contractors rely on PEX-to-FPT adapters when transitioning between flexible PEX supply lines and threaded copper, iron, or brass fittings. The non-swivel design means the fitting body does not rotate once installed, providing a fixed, secure connection point that holds its position during system assembly and operation. This is especially useful in tight spaces or where a stable, non-rotating joint is required for proper alignment. The brass construction gives this adapter excellent corrosion resistance, long service life, and compatibility with potable water systems. Brass fittings are a preferred choice for plumbing professionals because they handle a wide range of water temperatures and pressures without degrading. The 1/2 inch PEX end connects to standard 1/2 inch PEX-A, PEX-B, or PEX-C tubing using a compatible crimp ring, clamp ring, or expansion fitting tool depending on the installation method. The 3/4 inch FPT end threads onto any standard 3/4 inch male-threaded fitting or valve. This adapter is well suited for water supply lines, hydronic heating systems, and general plumbing rough-in work. Having the right adapter on hand keeps jobs moving without delays. The 105246-lf is a direct, no-frills solution for a common transition point found throughout plumbing systems of all sizes.

• Connects 1/2 inch PEX tubing to 3/4 inch female pipe thread (FPT) fittings
