Constructed from modified polyphenylsulfone (MPPSU), this fitting connects three pipe runs at different diameters: 1-1\/2 inches, 1-1\/4 inches, and 1 inch nominal sizes. The ProPEX end style requires a ProPEX expansion tool to expand the pipe and sleeve before insertion, creating a strong, reliable joint as the material returns to its original size. Licensed plumbers and mechanical contractors install this fitting in hydronic heating, potable water distribution, and radiant systems where reducing branch connections are needed.\u003c\/p\u003e\u003cp\u003eThis reducing tee is suited for residential and light commercial plumbing and hydronic applications where flow must be distributed or reduced across three pipe sizes in a single fitting. The ProPEX connection method is common in new construction and retrofit projects using Uponor PEX-a pipe. The fitting is domestically manufactured, which may satisfy Buy American or project specification requirements on applicable job sites.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThree-way reducing configuration: 1-1\/2 x 1-1\/4 x 1 inch nominal\u003c\/li\u003e\n\u003cli\u003eProPEX end style for use with PEX-a expansion tooling\u003c\/li\u003e\n\u003cli\u003eModified polyphenylsulfone construction for high-temperature and chemical resistance\u003c\/li\u003e\n\u003cli\u003eDomestic manufacture supports project compliance specifications\u003c\/li\u003e\n\u003cli\u003eCompatible with Uponor ProPEX expansion system components\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Uponor ProPEX PEX-a piping systems at the nominal pipe sizes specified: 1-1\/2 inch, 1-1\/4 inch, and 1 inch.

Shut off and depressurize the water supply or hydronic system before making any connections. Work should be performed by a licensed plumber in accordance with local plumbing codes and applicable IPC or IMC requirements. Allow expanded joints adequate time to recover before pressure testing the system.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1-1\/2 x 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: Modified Polyphenylsulfone (MPPSU)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Domestic\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: Q4751531\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"UPONOR","offers":[{"title":"Default Title","offer_id":51525439127858,"sku":"PLTRED1121141","price":28.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d9801e4e4439642d1a8010b7b13e4839_a6c91dda-6fc0-4917-83b3-0de38b69c33e.jpg?v=1785473739","url":"https:\/\/voomisupply.com\/products\/uponor-q4751531-reducing-tee-1-1-2x1-1-4x1-in-propex","provider":"Voomi Supply","version":"1.0","type":"link"}
