It transitions from a 1-1\/2 inch nominal pipe connection down to a 1-1\/4 inch nominal pipe connection, allowing plumbers and mechanical contractors to reduce line size within a system without additional adapters. The fitting is manufactured from modified polyphenylsulfone (MPPSU), a high-performance thermoplastic that offers excellent resistance to heat, pressure, and chlorinated water. This fitting is domestically manufactured and suited for potable water and hydronic distribution applications.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is intended for use in residential and light commercial plumbing and hydronic systems where PEX piping is installed using the ProPEX expansion method. Typical applications include main-to-branch transitions in domestic hot and cold water distribution lines and in-floor or panel heating systems where a step-down in pipe diameter is required. Installation is performed by licensed plumbers or mechanical contractors using a ProPEX expansion tool and the appropriate ring size for each end of the fitting.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces from 1-1\/2 inch nominal to 1-1\/4 inch nominal in a single fitting\u003c\/li\u003e\n  \u003cli\u003eProPEX end style for use with PEX expansion tooling\u003c\/li\u003e\n  \u003cli\u003eModified polyphenylsulfone construction for high heat and chemical resistance\u003c\/li\u003e\n  \u003cli\u003eDomestically manufactured\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard ProPEX expansion rings for each respective pipe size\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style fitting for ProPEX expansion-method PEX piping systems using 1-1\/2 inch and 1-1\/4 inch nominal pipe sizes.\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 ASTM F1960 expansion fitting standards. Shut off the water supply and depressurize the line before cutting or fitting. Use the correct ProPEX expansion tool and rings sized to match each end of the fitting. Allow the expanded PEX ring to recover fully 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\/2 x 1-1\/4 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 (MPPSU)\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: Q4771513\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"UPONOR","offers":[{"title":"Default Title","offer_id":51525205492018,"sku":"PLRED112114","price":17.22,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97355d283628dd92a10fe31012cf679f_2a946eff-bf60-40cd-9b05-763e60ce0cbc.jpg?v=1785467169","url":"https:\/\/voomisupply.com\/products\/uponor-q4771513-reducing-coupling-1-1-2-x-1-1-4-in-propex","provider":"Voomi Supply","version":"1.0","type":"link"}
