This fitting is manufactured from domestic brass stock and carries a lead-free designation, making it suitable for use in potable water systems where compliance with lead-free standards is required. Plumbers and pipefitters install this adapter when connecting PEX distribution lines to threaded valves, manifolds, or fixtures. The PEX end accepts an Uponor expansion-style connection, while the male NPT end threads directly into a female-threaded fitting or valve body.\u003c\/p\u003e\u003cp\u003eThis adapter is used in residential and light commercial plumbing systems where PEX tubing is the primary distribution material. Typical applications include domestic hot and cold water supply lines, in-wall rough-in work, and connections to shut-off valves or fixture supply stops. The 1\/2 inch size is the most common size in residential potable water distribution, making this fitting a high-frequency item in new construction and remodel work alike.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLead-free brass construction meets potable water compliance requirements\u003c\/li\u003e\n\u003cli\u003e1\/2 inch PEX inlet transitions to 1\/2 inch male NPT outlet\u003c\/li\u003e\n\u003cli\u003eDomestically manufactured brass fitting\u003c\/li\u003e\n\u003cli\u003eCompatible with Uponor PEX expansion fitting systems\u003c\/li\u003e\n\u003cli\u003eMale NPT thread allows direct connection to standard female-threaded valves and fittings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style transition fitting for 1\/2 inch Uponor PEX expansion systems connecting to male NPT-threaded plumbing components.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with applicable IPC or local plumbing codes.
