This fitting is domestically manufactured and built for use in potable water systems where lead-free compliance is required. The brass construction provides corrosion resistance and long service life in both hot and cold water applications. Plumbers and pipefitters use this adapter when connecting PEX distribution lines to existing copper supply runs or copper-terminated fixtures, making it a common component in residential remodel and new construction plumbing work.\u003c\/p\u003e\n\u003cp\u003eThis adapter is suited for residential and light commercial plumbing installations where PEX tubing meets copper pipe at a transition point. Typical applications include under-sink supply connections, branch line transitions, and fixture tie-ins where the supply side is copper and the distribution side is PEX. The sweat end accepts standard 1\/2-inch copper solder fittings, while the PEX end is sized for 3\/8-inch PEX expansion or crimp installation depending on the compatible Uponor system used.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLead-free brass construction meets federal and state lead-free requirements for potable water contact\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch PEX inlet x 1\/2-inch copper sweat outlet transition\u003c\/li\u003e\n  \u003cli\u003eDomestic manufacture supports project compliance requirements\u003c\/li\u003e\n  \u003cli\u003eSweat end compatible with standard 1\/2-inch copper solder connections\u003c\/li\u003e\n  \u003cli\u003eSuitable for both hot and cold potable water service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style transition fitting for 3\/8-inch PEX tubing systems connecting to 1\/2-inch copper pipe in residential and light commercial plumbing applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with local plumbing codes and the IPC.
