The EFF 105266-lf is a non-swivel adapter fitting designed to connect 3/4 inch PEX tubing to a female pipe thread (FPT) fitting. Made entirely from brass, this adapter is built for reliable performance in residential and commercial plumbing systems. It provides a fixed, non-rotating connection that eliminates movement at the joint, which helps prevent leaks over the long term. Plumbers and pipefitters rely on this type of fitting when transitioning from flexible PEX supply lines to threaded pipe connections at valves, manifolds, shutoffs, or fixture inlets. The 3/4 inch size is one of the most common dimensions used in main water supply lines, making this adapter a staple in both new construction and retrofit plumbing work. Brass is the material of choice for PEX adapters because it resists corrosion from water, handles wide temperature swings, and holds up well under sustained pressure. Unlike plastic alternatives, a brass fitting will not crack or become brittle in cold environments or high-temperature domestic hot water applications. The female pipe thread end accepts a standard NPT male fitting, allowing easy connection to threaded valves, tees, elbows, or other pipe components. The PEX end is designed for use with crimp or clamp ring systems, depending on the installation method used on the job. This fitting is lead-free, making it suitable for potable water systems where code compliance and public health standards require low-lead materials. HVAC technicians also use PEX-to-FPT adapters when connecting radiant heating loops to manifold systems. Keep this fitting on hand for rough-in plumbing, remodeling projects, and service calls where a solid PEX-to-threaded transition is needed.
The EFF 105266-lf delivers a dependable, lead-free brass transition from 3/4 inch PEX tubing to female pipe thread, suited for potable water, radiant heat, and general plumbing applications.
