Eff 104067-lf Brass Pex X Mpt Adapter 3/4 in Pex X 1 in Mpt

Product Description

The EFF 104067-lf is a brass adapter fitting designed to connect 3/4 inch PEX tubing to a 1 inch male pipe thread (MPT) connection. This fitting is a reliable solution for plumbers and pipefitters who need to transition between PEX supply lines and threaded pipe fittings in residential and commercial plumbing systems. PEX-to-MPT adapters like this one are commonly used at water heater connections, shutoff valve installations, manifold hookups, and other points where flexible PEX tubing meets a threaded fixture or valve body. The 104067-lf is manufactured from solid brass, a material well suited for potable water systems due to its corrosion resistance, durability, and ability to maintain a leak-free seal under normal working pressures. Brass fittings hold up well in both hot and cold water applications, making this adapter a versatile choice across a wide range of plumbing jobs. The PEX side of the fitting accepts 3/4 inch PEX tubing and is compatible with standard PEX crimping or clamp ring installation methods, depending on the installer's preferred tooling. The male pipe thread end measures 1 inch and is designed to thread directly into a female-threaded port on a valve, manifold, water heater, or similar fixture. The size transition from 3/4 inch PEX to 1 inch MPT is a common configuration in plumbing rough-in work, particularly when connecting PEX distribution lines to larger-ported equipment or fittings. This adapter helps reduce the need for additional transition fittings and simplifies the installation process. Plumbers working on PEX repipes, new construction rough-in, or retrofit projects will find this fitting straightforward to install and dependable in service.
