SHARKBITE UC058LFA — 1/2 IN × 3/4 IN LEAD‑FREE PEX REDUCING COUPLING

The SharkBite UC058LFA is a 1/2‑inch × 3/4‑inch reducing PEX coupling designed to transition between two different sizes of PEX tubing within potable‑water or hydronic‑heating systems. Constructed from lead‑free DZR brass, this fitting delivers long‑term durability, corrosion resistance, and reliability for both residential and commercial plumbing applications.

The UC058LFA uses standard PEX crimp or clamp connection methods, making installation quick, consistent, and tool‑friendly. Its dual barb design ensures a secure mechanical seal on both pipe sizes without the need for solder, glue, or heat. This coupling is compatible with PEX‑A, PEX‑B, and PEX‑C, allowing versatile use across multiple system types.

Rated for demanding environments up to 200°F and 160–200 PSI (depending on system conditions), the UC058LFA performs reliably in potable‑water distribution, radiant‑heat loops, and other closed‑loop heating systems. Its compact form factor makes it ideal for tight spaces and retrofit work where size transitions are required.
