Product details

A 3/4″ PEX female brass adaptor is a fitting used to connect a PEX pipe to a component with 3/4‑inch male threads (for example a valve or threaded fitting). The adaptor is made of lead‑free brass for durability and corrosion resistance in potable water systems. One end (the PEX side) is designed to accept the PEX tubing—commonly via a barb, crimp, or expansion connection—and the other end features internal (female) threads that match standard 3/4‑inch male pipe threads (often NPT). Proper installation requires securing the PEX side with the appropriate ring or clamp and using thread sealant (e.g. PTFE tape) on the male threads to ensure a leak‑tight seal. When selected correctly for pressure and temperature ratings, this fitting enables integration of flexible PEX piping into systems with threaded plumbing components.
