Built from lead-free brass, this fitting meets drinking water safety requirements for potable water systems. The ProPEX end expands and connects using the Uponor ProPEX expansion method, while the copper end accepts a standard press or sweat connection. Licensed plumbers install this adapter in residential and light commercial plumbing systems where PEX distribution lines terminate at copper stub-outs, manifolds, or fixture supply connections.\u003c\/p\u003e\n\u003cp\u003eThis adapter is suited for potable water supply systems, hydronic heating distribution, and mixed-material plumbing layouts where PEX tubing meets existing copper infrastructure. It is a domestically sourced fitting, making it appropriate for projects subject to Buy American provisions or local procurement requirements. The lead-free brass construction satisfies NSF 61 and NSF 372 low-lead content thresholds applicable to wetted components in drinking water systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-inch PEX by 3\/4-inch copper nominal size transition\u003c\/li\u003e\n  \u003cli\u003eLead-free brass construction for potable water compliance\u003c\/li\u003e\n  \u003cli\u003eProPEX expansion end compatible with Uponor ProPEX expansion tooling\u003c\/li\u003e\n  \u003cli\u003eCopper end accepts press or sweat connection methods\u003c\/li\u003e\n  \u003cli\u003eDomestically sourced fitting suitable for Buy American project requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style transition fitting for 3\/4-inch ProPEX PEX tubing systems connecting to 3\/4-inch copper pipe in residential and light commercial plumbing applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a licensed plumber and the appropriate Uponor ProPEX expansion tool to expand the PEX end before seating the fitting.
