AdaptProPEX LF Brass Sweater 3/4 " PEX x 3/4" Copper

ProPEX LF Brass Sweat Adapter 3/4 " PEX x 3/4" Copper

The Uponor is a lead-free brass adapter designed to transition from 3/4″ PEX (e.g. Uponor AquaPEX®) tubing to 3/4″ copper pipe ideal for potable hot or cold water distribution, hydronic heating, radiant floor systems, and fire-safe installations. The fitting uses the ProPEX® expansion end for reliable, torch-free connections to PEX, and a female sweat end that slips over copper pipe for soldering. Because the adapter is made from lead-free brass and meets multiple plumbing standards, it’s safe for direct burial and long-term water use.
