Constructed from modified polyphenylsulfone (PPSU), this fitting offers strong resistance to heat and pressure typical of residential and light commercial plumbing and hydronic applications. The ProPEX end style requires an expansion tool to form the connection, creating a reliable, leak-resistant joint as the PEX pipe memory causes it to compress tightly around the fitting. Licensed plumbers and pipefitters install this coupling when joining two sections of PEX tubing of the same diameter or restoring continuity after a pipe repair.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for residential and light commercial potable water distribution, radiant heating, and hydronic piping systems where 1-1\/2 inch PEX tubing is specified. The ProPEX expansion method is commonly used in new construction and remodel work where reliable, high-cycle connections are required. Domestic manufacturing supports projects with domestic-content compliance requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/2 inch nominal size for direct coupling of same-diameter PEX tubing\u003c\/li\u003e\n  \u003cli\u003eProPEX expansion end style for a secure, memory-fit mechanical connection\u003c\/li\u003e\n  \u003cli\u003eModified polyphenylsulfone (PPSU) construction for high heat and pressure resistance\u003c\/li\u003e\n  \u003cli\u003eDomestically manufactured to support buy-domestic project specifications\u003c\/li\u003e\n  \u003cli\u003eCompatible with ProPEX expansion tooling for consistent installation results\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style ProPEX fitting for use with 1-1\/2 inch PEX tubing in systems requiring the ProPEX expansion connection method.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a calibrated ProPEX expansion tool sized for 1-1\/2 inch tubing. Shut off the water supply and depressurize the line before cutting into existing piping. Expand the PEX pipe end, seat the fitting fully, and allow the pipe memory to compress around the fitting before pressurizing. Work must comply with applicable local plumbing codes and IPC requirements for PEX installations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: ProPEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Modified Polyphenylsulfone (PPSU)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrigin\u003c\/strong\u003e: Domestic\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: UPONOR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: Q4771515\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"UPONOR","offers":[{"title":"Default Title","offer_id":51524924342578,"sku":"PLCOUP112","price":17.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97355d283628dd92a10fe31012cf679f_db30a599-169f-4bc8-a36f-c63792ac6ff4.jpg?v=1785461830","url":"https:\/\/voomisupply.com\/products\/uponor-q4771515-propex-coupling-1-1-2-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
