It connects 1\/2-inch PEX tubing on one end to 3\/4-inch PEX tubing on the other, allowing trades to transition between two common pipe sizes within a single fitting. Constructed from lead-free brass, it meets drinking water safety requirements for potable water applications. This coupling is installed using the ProPEX expansion method, where a ProPEX tool expands the PEX ring and pipe end before the fitting is inserted and the ring contracts to form a secure, leak-resistant joint.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for residential and light commercial plumbing systems where a size transition between 1\/2-inch and 3\/4-inch PEX lines is required. Typical applications include domestic hot and cold water distribution, hydronic radiant heating supply and return lines, and branch-to-main transitions. It is installed by licensed plumbers and pipefitters working with Uponor ProPEX expansion tooling and compatible PEX-a tubing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLead-free brass construction meets potable water safety standards\u003c\/li\u003e\n  \u003cli\u003eReduces from 3\/4 inch to 1\/2 inch for branch or transition connections\u003c\/li\u003e\n  \u003cli\u003eCompatible with ProPEX expansion installation method\u003c\/li\u003e\n  \u003cli\u003eSuitable for both hot and cold water service lines\u003c\/li\u003e\n  \u003cli\u003eDesigned for use with PEX-a tubing in Uponor ProPEX systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style fitting for use in Uponor ProPEX PEX-a plumbing and radiant heating systems requiring a 1\/2-inch by 3\/4-inch reducing coupling connection.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed plumber using Uponor-approved ProPEX expansion tooling. Shut off the water supply and relieve system pressure before beginning work. The ProPEX expansion ring must be fully seated before inserting the fitting, and the joint should be allowed to contract fully before pressure testing. Follow all applicable local plumbing codes and ASTM standards for PEX piping installations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 1\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 2\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: ProPEX Expansion\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Lead-Free Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Potable Water, Radiant Heating\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: WIRLFRED3412\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"UPONOR","offers":[{"title":"Default Title","offer_id":51525094277426,"sku":"LFRED3412","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/076889a87b44d290c7d992b470e99885.jpg?v=1785464217","url":"https:\/\/voomisupply.com\/products\/uponor-wirlfred3412-propex-lead-free-brass-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
