SHARKBITE UC134LFA — 3/4 IN × 3/4 IN PEX BARB × MNPT ADAPTER (LEAD‑FREE DZR BRASS)

The SharkBite UC134LFA is a 3/4‑inch PEX barb × 3/4‑inch MNPT threaded male adapter designed to provide a secure transition between PEX tubing and female‑threaded plumbing components. Manufactured from lead‑free DZR brass, this fitting delivers long‑term durability, corrosion resistance, and compliance for potable‑water and hydronic‑heating systems.

This adapter connects to PEX using standard crimp or clamp methods, making it compatible with all PEX A, B, and C systems. The barb end ensures a solid mechanical seal with PEX tubing, while the MNPT threaded end provides a tight, reliable metal‑to‑metal connection. Rated for high temperature and pressure service, the UC134LFA is suitable for residential and commercial plumbing installations.

Its full‑flow interior design maintains pressure and system performance, while the compact hex‑body profile allows easy wrench access during installation. This fitting is commonly used for water heater hookups, manifolds, valve connections, and general plumbing transitions requiring a threaded male end.
