This fitting allows a technician to transition between a solder-joint copper line and a threaded female port within the same assembly. Cast copper construction provides the durability and pressure resistance required in plumbing, HVAC hydronic, and refrigeration piping systems. Licensed plumbers and HVAC pipefitters install this type of bushing wherever a size reduction and a sweat-to-thread transition are needed at a single connection point.\u003c\/p\u003e\n\u003cp\u003eThis flush bushing is suited for residential and light commercial plumbing systems, hydronic heating loops, and copper distribution piping where a 1-1\/4 inch sweat fitting end must connect to a 3\/4 inch female-threaded component such as a valve, gauge, or threaded fitting. The sweat FTG end is sized to slip inside a standard 1-1\/4 inch copper fitting socket, making it compatible with standard copper tube and fitting assemblies following ASME B16.22 dimensional standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCast copper construction for reliable performance in pressurized piping systems\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch sweat fitting (FTG) inlet transitions to 3\/4 inch female pipe thread (FPT) outlet\u003c\/li\u003e\n  \u003cli\u003eFlush bushing profile sits flush within the mating fitting socket\u003c\/li\u003e\n  \u003cli\u003eSweat end accepts standard solder-joint assembly per ASTM and ASME practices\u003c\/li\u003e\n  \u003cli\u003eFPT outlet accommodates standard NPT-threaded male connections\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for standard 1-1\/4 inch copper sweat fitting assemblies requiring a 3\/4 inch female NPT threaded outlet.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber or qualified HVAC pipefitter. Shut off and depressurize the system and drain standing water before soldering. Clean and flux both the FTG end and the receiving fitting socket before applying heat to ensure a leak-free solder joint. Apply thread sealant tape or compound to the male fitting being threaded into the FPT end and tighten per applicable IPC or IFGC guidelines.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 1-1\/4 inches (SWT FTG)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 3\/4 inches (FPT)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Sweat Fitting x Female Pipe Thread\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Style\u003c\/strong\u003e: Flush Bushing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast Copper\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: NIBCO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: b179400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51234004009266,"sku":"B179400","price":33.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307629439.jpg?v=1780114677","url":"https:\/\/voomisupply.com\/products\/nibco-b179400-flush-bushing-1-1-4-x-3-4-in-copper-swt-x-fpt","provider":"Voomi Supply","version":"1.0","type":"link"}
