It transitions from a 1-1\/4 inch nominal pipe to a 1 inch nominal pipe using the ProPEX end style, which requires a ProPEX expansion tool and corresponding PEX rings for installation. The fitting body is constructed from polysulfone and modified polyphenylsulfone, materials chosen for their resistance to high temperatures, chlorine, and pressure cycling common in residential and light commercial plumbing applications. Licensed plumbers and pipefitters are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is used wherever a ProPEX PEX-a piping system requires a step-down in pipe diameter, such as transitioning from a main distribution line to a branch line. Typical applications include domestic hot and cold water supply, radiant heating distribution manifolds, and hydronic systems. The domestic designation indicates this fitting is manufactured in the United States, which may be relevant for projects with domestic content requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces from 1-1\/4 inch nominal to 1 inch nominal in a single fitting\u003c\/li\u003e\n  \u003cli\u003eProPEX end style for use with PEX-a tubing and expansion rings\u003c\/li\u003e\n  \u003cli\u003ePolysulfone and modified polyphenylsulfone construction for thermal and chemical resistance\u003c\/li\u003e\n  \u003cli\u003eDomestically manufactured fitting\u003c\/li\u003e\n  \u003cli\u003eNo metal components to corrode or dezincify in aggressive water conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with UPONOR ProPEX PEX-a tubing systems requiring a 1-1\/4 inch to 1 inch reducing connection using the ProPEX expansion method.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a calibrated ProPEX expansion tool and the correct size PEX expansion rings for both the 1-1\/4 inch and 1 inch ends. Shut off the water supply and depressurize the line before cutting into any existing piping. Work must be performed by a licensed plumber in accordance with applicable local plumbing codes and the IPC. Allow expanded PEX rings to fully contract around the fitting before pressurizing the system.\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\/4 x 1 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: Polysulfone \/ Modified Polyphenylsulfone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrigin\u003c\/strong\u003e: Domestic (USA)\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: Q4771310\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"UPONOR","offers":[{"title":"Default Title","offer_id":51525293769010,"sku":"PLRED1141","price":15.2,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97355d283628dd92a10fe31012cf679f_1c5e5246-ed82-447a-8892-d19751dd0126.jpg?v=1785469824","url":"https:\/\/voomisupply.com\/products\/uponor-q4771310-reducing-coupling-1-1-4-x-1-inch-propex","provider":"Voomi Supply","version":"1.0","type":"link"}
