SHARKBITE UC530LFA — 3/4 IN × 3/4 IN PEX SWIVEL ADAPTER (FNPT, LEAD‑FREE DZR BRASS)

The SharkBite UC530LFA is a 3/4‑inch PEX barb × 3/4‑inch FNPT swivel adapter designed to connect PEX tubing to a male‑threaded fitting. This versatile fitting features a swivel FNPT nut, allowing the installer to rotate and tighten the connection without twisting the PEX line—ideal for tight spaces and fixture hookups.

Constructed from lead‑free DZR brass, the adapter delivers excellent corrosion resistance and long‑term reliability. It is suitable for both potable‑water systems and hydronic heating applications. The barb end is compatible with standard crimp or clamp ring systems, making installation simple and secure.

This fitting is commonly used for water‑heater connections, manifolds, appliance hookups, hose interfaces, and any point where PEX transitions to a threaded female swivel connection.
