Eff 104077-lf 1 Inch Pex X Mpt Brass Adapter Lead-free Fitting

Product Description

The EFF 104077-lf is a 1 inch PEX x 1 inch MPT brass adapter fitting designed for reliable transitions between PEX tubing and male pipe threaded connections. This lead-free brass adapter is built for residential and commercial plumbing systems where a secure, code-compliant connection is required. Plumbers and pipe fitters rely on PEX-to-MPT adapters like this one to join flexible PEX supply lines to threaded fixtures, valves, water heaters, and manifolds. The 104077-lf handles both hot and cold water applications with equal reliability, making it a go-to fitting for new construction and retrofit plumbing projects alike. Brass construction provides excellent corrosion resistance and long service life, even in demanding water conditions. The male pipe thread on one end allows straightforward connection to standard NPT-threaded ports found on most fixtures and equipment. The PEX end is sized at 1 inch to match standard PEX-A, PEX-B, and PEX-C tubing, giving installers flexibility across different PEX system types. This adapter is a critical component when transitioning from a PEX distribution system to a threaded termination point, such as at a shutoff valve, pressure regulator, or fixture connection. Lead-free brass meets NSF 61 and NSF 372 standards typically required for potable water use in modern plumbing codes. The fitting is compact and straightforward to install, reducing labor time on the job. Whether working on a residential water supply rough-in or a light commercial plumbing system, the EFF 104077-lf delivers a durable, leak-resistant joint that professionals trust. This part is a standard inventory item for plumbing contractors handling PEX-based distribution systems.
