Eff 104044-lf Brass Pex X Mpt Adapter 1/2 Inch X 1/2 Inch

Product Description

The EFF 104044-lf is a brass adapter fitting designed for connecting 1/2 inch PEX tubing to a 1/2 inch male pipe thread (MPT) fitting. This type of transition adapter is a core component in residential and commercial plumbing systems where PEX supply lines meet threaded metal connections. Plumbers, pipefitters, and mechanical contractors rely on PEX-to-MPT adapters like the 104044-lf to make clean, reliable transitions between flexible PEX runs and threaded valves, manifolds, shutoff valves, water heaters, and fixture supply connections. PEX tubing has become the standard choice for potable water distribution in new construction and remodel work due to its flexibility, freeze resistance, and ease of installation. When that PEX line needs to connect to a fixed threaded port, a brass adapter fitting is the go-to solution. Brass is widely preferred for these fittings because of its strength, corrosion resistance, and compatibility with both hot and cold water systems. The 104044-lf is lead-free compliant, making it suitable for use in potable water applications where lead-free standards are required by local plumbing codes. The PEX end of this fitting accepts standard 1/2 inch PEX tubing using the appropriate crimp ring or clamp method, while the MPT end threads directly into a female-threaded port. This combination gives installers a straightforward, code-compliant way to terminate PEX lines at threaded connection points. Whether roughing in a new bathroom, replacing supply lines under a sink, or connecting a water heater, this adapter delivers a durable and watertight joint. The all-brass construction ensures long service life in demanding plumbing environments.
