This fitting connects two sections of 1-inch PEX tubing using the ProPEX expansion method, where a ProPEX tool expands the tubing end before the fitting is inserted and the tubing contracts to form a secure, leak-resistant joint. Constructed from lead-free brass, this coupling meets domestic sourcing requirements. It is a standard component installed by licensed plumbers in both new construction and retrofit applications.\u003c\/p\u003e\u003cp\u003eThis coupling is suited for residential and light commercial plumbing installations where ProPEX-style PEX piping is specified. It is commonly used in water supply distribution systems, including hot and cold potable water lines. The ProPEX expansion connection method is widely used in hydronic and domestic water applications where a reliable, tool-driven mechanical joint is preferred over crimp or clamp alternatives.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-inch nominal size for standard ProPEX PEX tubing connections\u003c\/li\u003e\n\u003cli\u003eProPEX end style requires a ProPEX expansion tool for installation\u003c\/li\u003e\n\u003cli\u003eLead-free brass construction meets potable water safety requirements\u003c\/li\u003e\n\u003cli\u003eDomestic product sourcing\u003c\/li\u003e\n\u003cli\u003eCoupling configuration joins two inline pipe sections\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 1-inch ProPEX-compatible PEX tubing in residential and commercial plumbing systems using the ProPEX expansion connection method.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a calibrated ProPEX expansion tool sized for 1-inch tubing. Licensed plumbers should shut off the water supply and depressurize the line before beginning work. All installations must comply with applicable local plumbing codes and IPC requirements. Allow adequate expansion ring seating time as specified by system installation guidelines before pressurizing the system.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1 inch\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\u003eOrigin\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: LF4541010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"UPONOR","offers":[{"title":"Default Title","offer_id":51525237342514,"sku":"LFCOUP1","price":15.23,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8d151fc17fb882a575919db538ca7fba_a2c00ff1-bfd8-4136-95ef-2d5c4f9c4d0a.jpg?v=1785468083","url":"https:\/\/voomisupply.com\/products\/uponor-lf4541010-propex-brass-coupling-1-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
