Constructed from modified polyphenylsulfone (MPPSU), this fitting provides a durable, corrosion-resistant connection at three ports with nominal sizes of 1-1\/2 inches, 1-1\/4 inches, and 3\/4 inches. ProPEX end connections require an expansion tool to expand the pipe and ring before seating the fitting, creating a strong, leak-resistant joint as the material recovers. Licensed plumbers and hydronic system installers work with this fitting in both new construction and retrofit applications.\u003c\/p\u003e\n\u003cp\u003eThis reducing tee is suited for residential and light commercial plumbing and hydronic heating distribution systems where branch takeoffs at reduced diameters are needed. The 3\/4-inch branch outlet allows a smaller supply or return line to split from a larger 1-1\/2-inch main run, with the 1-1\/4-inch outlet continuing the reduced main. It is commonly used in manifold-fed systems, radiant heating loops, and domestic water distribution where flow balancing across multiple zones is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThree-port reducing configuration: 1-1\/2 x 1-1\/4 x 3\/4 inches nominal\u003c\/li\u003e\n  \u003cli\u003eProPEX expansion end style for reliable, tool-expanded connections\u003c\/li\u003e\n  \u003cli\u003eModified polyphenylsulfone construction offers high heat and chemical resistance\u003c\/li\u003e\n  \u003cli\u003eCorrosion-free material suitable for potable water and hydronic fluid contact\u003c\/li\u003e\n  \u003cli\u003eDomestic manufacture\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 Uponor ProPEX PEX-a pipe and compatible expansion rings at the stated nominal sizes of 1-1\/2 inches, 1-1\/4 inches, and 3\/4 inches.\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 each port. Shut off the water supply and depressurize the line before cutting into any existing piping. Work should be performed by a licensed plumber in accordance with applicable local plumbing codes and ASTM F1960 expansion fitting standards. Allow expanded connections to fully recover before pressurizing the system.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: ProPEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1-1\/2 x 1-1\/4 x 3\/4 inches\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\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: Q4751537\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"UPONOR","offers":[{"title":"Default Title","offer_id":51524537712946,"sku":"PLTRED11211434","price":28.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d9801e4e4439642d1a8010b7b13e4839_7691e5be-aaed-4f4e-bd0b-fd57aa74b536.jpg?v=1785451213","url":"https:\/\/voomisupply.com\/products\/uponor-q4751537-reducing-tee-1-1-2x1-1-4x3-4-in-propex","provider":"Voomi Supply","version":"1.0","type":"link"}
