SHARKBITE UC120LFA — 1/2 IN × 1/2 IN PEX BARB × MNPT ADAPTER (LEAD‑FREE DZR BRASS)

The SharkBite UC120LFA is a 1/2‑inch PEX barb × 1/2‑inch MNPT threaded male adapter engineered to provide a durable, secure transition between PEX tubing and female‑threaded plumbing components. Manufactured from lead‑free DZR brass, this fitting offers exceptional corrosion resistance and long‑term reliability for both potable‑water and hydronic‑heating systems.

Designed for use with standard crimp or clamp PEX connection systems, the UC120LFA supports PEX‑A, PEX‑B, and PEX‑C installations. Its barb end creates a strong mechanical connection to PEX tubing, while the MNPT end delivers a dependable threaded seal. Compact and wrench‑friendly, the hex‑body design aids installation even in tight spaces.

Rated up to 200°F and 160 PSI, this adapter performs consistently in residential and commercial plumbing, including water heaters, manifolds, valves, and fixture transitions. Its full‑flow internal geometry helps preserve system pressure and efficiency.
