About this item

SHARKBITE UC138LFA — 3/4 IN × 1/2 IN PEX BARB × MNPT ADAPTER (LEAD‑FREE DZR BRASS)

The SharkBite UC138LFA is a 3/4‑inch PEX barb × 1/2‑inch MNPT reducing male adapter designed for transitioning from PEX tubing to a female‑threaded connection. Its durable lead‑free DZR brass construction provides long‑term resistance to corrosion and scale, making it suitable for potable water systems, hydronic heating, and radiant installations.

This adapter uses the standard crimp or clamp PEX connection method, allowing flexibility across PEX A/B/C systems. The barb end ensures a secure mechanical grip on PEX tubing, while the male NPT end threads directly into compatible fittings or fixtures. Rated for high temperature and pressure, the UC138LFA offers reliable performance in both residential and commercial plumbing applications.

The fitting is ideal for connecting PEX pipe to water heaters, manifolds, valves, or any transition requiring a threaded connection. Its compact design helps reduce installation space while maintaining a full‑flow pathway.
