It transitions between 1-inch and 3\/4-inch nominal pipe sizes, making it a standard fitting for residential and light commercial plumbing distribution layouts where supply lines step down to branch lines. The lead-free brass construction meets drinking water compliance requirements, and the ProPEX end style requires a compatible PEX expansion tool and rings for installation. This coupling is domestically manufactured and suited for potable water, hydronic, and radiant heating applications.\u003c\/p\u003e\n\u003cp\u003eThis fitting is used in plumbing and hydronic systems where a size reduction is needed between a main run and a branch connection. Typical installations include residential water distribution systems, in-floor radiant heating manifold branches, and potable water supply rough-ins where 1-inch mains feed 3\/4-inch branch lines. The ProPEX connection method provides a reliable, expansion-based joint that does not require solvents, clamps, or crimping tools.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces from 1-inch to 3\/4-inch nominal pipe size in a single fitting\u003c\/li\u003e\n  \u003cli\u003eLead-free brass construction meets potable water compliance standards\u003c\/li\u003e\n  \u003cli\u003eProPEX expansion end style for use with UPONOR-compatible PEX expansion tools and rings\u003c\/li\u003e\n  \u003cli\u003eDomestic manufacture supports project specifications requiring USA-made components\u003c\/li\u003e\n  \u003cli\u003eSuitable for potable water, hydronic, and radiant heating piping systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ProPEX expansion-style PEX tubing systems in 3\/4-inch and 1-inch nominal sizes.

Shut off and depressurize the water supply before cutting into an existing line. Work must comply with local plumbing codes, which typically reference IPC or UPC standards for PEX installations. Allow expanded PEX connections to recover fully 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: 3\/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: Lead-Free Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Domestic (USA)\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: LF4547510\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"UPONOR","offers":[{"title":"Default Title","offer_id":51524823974194,"sku":"LFRED134","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8d151fc17fb882a575919db538ca7fba_8bcf3381-ee9d-4d11-8b29-f64c96f022e1.jpg?v=1785458669","url":"https:\/\/voomisupply.com\/products\/uponor-lf4547510-reducing-coupling-3-4-x-1-in-propex-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
