Built to ANSI B16.3 dimensional standards, it handles temperatures from -20 degrees F to 350 degrees F, making it suitable for steam, gas, air, and water service applications. The black finish malleable iron construction provides durability and corrosion resistance appropriate for industrial and commercial pipe runs. Licensed plumbers and pipefitters install this fitting as part of threaded iron distribution systems where a reduction in pipe diameter is required.\u003c\/p\u003e\u003cp\u003eThis reducing coupling is used in residential and commercial applications where black malleable iron threaded pipe is the specified material, including natural gas distribution, compressed air lines, steam service, and hydronic heating systems. It is sized for the common 6-inch to 4-inch reduction and threads directly onto standard tapered NPT pipe ends. The 6-8 x 4-8 thread designation confirms compatibility with standard pipe threading on both connection sides.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e6 in FPT x 4 in FPT reducing connection for standard NPT threaded pipe\u003c\/li\u003e\n\u003cli\u003e150 lb pressure class rating per ANSI B16.3 dimensional standards\u003c\/li\u003e\n\u003cli\u003eMalleable iron construction with black finish for gas, steam, air, and water service\u003c\/li\u003e\n\u003cli\u003eTemperature range from -20 degrees F to 350 degrees F\u003c\/li\u003e\n\u003cli\u003e6-8 x 4-8 thread specification for consistent fitment on standard pipe ends\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard fitting for black 150 lb malleable iron threaded piping systems meeting ANSI B16.3 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC). Shut off and depressurize the piping system completely before removing or installing any threaded fitting. Apply an appropriate pipe thread sealant or PTFE tape rated for the service medium to all male threads before assembly. Do not over-tighten; follow standard wrench-tight practices appropriate for the pipe size and service pressure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size 1\u003c\/strong\u003e: 6 inches FPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size 2\u003c\/strong\u003e: 4 inches FPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Specification\u003c\/strong\u003e: 6-8 x 4-8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Class\u003c\/strong\u003e: 150 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Malleable Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimension Standard\u003c\/strong\u003e: ANSI B16.3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: -20 to 350 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 4.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 7.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 7.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11.04 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MIDLAND INDUSTRIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 65491\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67950089011506,"sku":"65491","price":418.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/96101a68c5e9c183a7c88062a7bb902d_a0c4cb95-e3c7-46b6-b305-aa6e87e501c1.jpg?v=1791706717","url":"https:\/\/voomisupply.com\/products\/midland-industries-65491-reducing-coupling-6x4-in-fpt-150lb","provider":"Voomi Supply","version":"1.0","type":"link"}
