It features a 3\/4 x 1\/2 x 3\/4 inch nominal configuration, allowing branch connections where a reduced 1\/2 inch outlet is needed off a 3\/4 inch main run. The fitting body is constructed from 20% glass-reinforced polymer, which provides dimensional stability and resistance to pressure and temperature cycling common in PEX distribution systems. Installation requires a compatible ProPEX expansion tool and rings. Licensed plumbers and pipefitters are the primary installers for this type of fitting.\u003c\/p\u003e\n\u003cp\u003eThis reducing tee is suited for potable water distribution, hydronic heating branch runs, and radiant system manifold connections where PEX tubing is the specified pipe material. The ProPEX end style requires expansion of the pipe and ring before the fitting is inserted, forming a leak-resistant mechanical joint as the expanded material recovers. The domestic designation indicates the 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\u003e3\/4 x 1\/2 x 3\/4 inch nominal reducing tee configuration for branch reduction off a main run\u003c\/li\u003e\n  \u003cli\u003eProPEX end style for use with the Uponor expansion tool and ProPEX rings\u003c\/li\u003e\n  \u003cli\u003e20% glass-reinforced polymer body for dimensional stability under thermal cycling\u003c\/li\u003e\n  \u003cli\u003eDomestic manufacture for projects with buy-domestic or specification requirements\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard PEX-a tubing used in potable water and hydronic systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in ProPEX PEX-a piping systems requiring a 3\/4 x 1\/2 x 3\/4 inch reducing tee connection.

Shut off the water supply and depressurize the system before beginning any fitting work. Use only the manufacturer-specified ProPEX expansion tool and correctly sized ProPEX rings to ensure a proper mechanical joint. Do not use compression or crimp-style tooling with ProPEX fittings.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 3\/4 x 1\/2 x 3\/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: 20% Glass-Reinforced Polymer\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: Q4757557\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"UPONOR","offers":[{"title":"Default Title","offer_id":51525178261810,"sku":"PLTRED341234","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f1335d41a6484af0669ffb448d3fbc27_e9453fc8-c243-4dc8-80c4-a75e81dd0979.jpg?v=1785466390","url":"https:\/\/voomisupply.com\/products\/uponor-q4757557-propex-reducing-tee-3-4x1-2x3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
