It measures 3\/4 inch on the fitting end and 1 inch on the male threaded end, making it a reducing adapter used to step up thread size while changing connection type. Built from cast copper conforming to ASTM B584, it is suited for potable water, hydronic, and general plumbing pressure applications. Licensed plumbers and pipefitters install this fitting in both new construction and retrofit work wherever a sweat-to-male-thread transition is required.\u003c\/p\u003e\n\u003cp\u003eThis adapter is used in residential and light commercial plumbing systems where copper supply lines must terminate at or connect to a male NPT threaded port. Typical install scenarios include water heater connections, valve hookups, manifold assemblies, and branch line transitions. The 3\/4 inch FTG socket receives a 3\/4 inch copper tube for soldering, while the 1 inch MNPT end threads into a female-threaded fitting, valve body, or equipment port. It is sold individually with a minimum order quantity of one.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCast copper construction meets ASTM B584 and ISO standards for pressure fittings\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch FTG socket accepts standard 3\/4 inch copper tube for sweat soldering\u003c\/li\u003e\n  \u003cli\u003e1 inch MNPT threaded outlet connects to female NPT valves, ports, or fittings\u003c\/li\u003e\n  \u003cli\u003eReducing adapter configuration allows size and connection-type transition in a single fitting\u003c\/li\u003e\n  \u003cli\u003ePressure fitting style rated for use in water supply and hydronic piping systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style pressure fitting for use in copper piping systems requiring a sweat-to-male-NPT transition; compatible with standard 3\/4 inch copper tube on the FTG end and any female NPT 1 inch threaded port or fitting on the threaded end.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber following applicable IPC and local plumbing code requirements. Shut off the water supply and depressurize the line before soldering or threading. Clean and flux the copper tube before inserting into the FTG socket, and apply thread sealant or PTFE tape to the MNPT threads before assembly. Do not overtighten threaded connections or apply heat near completed threaded joints.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 3\/4 inch x 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: FTG x MNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: MNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Pressure Fitting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASTM B584, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.27 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: B034100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51544220369202,"sku":"B034100","price":74.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/43655ea0bcaaa4ce4567981e12c27a76.jpg?v=1785925811","url":"https:\/\/voomisupply.com\/products\/nibco-b034100-cast-copper-adapter-3-4x1-in-ftg-x-mnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
