A close nipple has no unthreaded center section — threads run from both ends and nearly meet in the middle, making it the right choice when two fittings must be joined with minimal gap between them. Standard NPT threads on both ends allow the nipple to mate with any standard pipe thread fitting. Weighing approximately 0.398 pounds, this is a compact, purpose-built connector for iron pipe systems in gas, steam, and hydronic applications.\u003c\/p\u003e\u003cp\u003eThis nipple is used in residential and light commercial piping systems where space between fittings is limited. Typical applications include gas supply lines, hydronic heating loops, steam distribution headers, and industrial process piping. The black iron finish makes it appropriate for natural gas and propane distribution where galvanized fittings are not permitted by code. It is installed by licensed plumbers, pipefitters, and gas service technicians working on Schedule 40 iron pipe systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClose nipple configuration — no exposed unthreaded center, ideal for tight-clearance connections\u003c\/li\u003e\n\u003cli\u003eSchedule 40 wall thickness for standard-pressure iron pipe service\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating resists corrosion and meets requirements for gas piping applications\u003c\/li\u003e\n\u003cli\u003eStandard NPT threads on both ends for compatibility with any NPT fitting or valve\u003c\/li\u003e\n\u003cli\u003eMeets ASTM A53 welded steel pipe standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard stock fitting for Schedule 40 black iron pipe systems using NPT threaded connections in 2 inch pipe size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber, pipefitter, or gas technician in accordance with applicable local codes, the International Fuel Gas Code (IFGC), or the International Plumbing Code (IPC). Shut off gas supply or depressurize the pipe system completely before disassembling any threaded connections. Apply an approved pipe thread sealant or PTFE tape rated for the service medium — confirm the sealant is listed for gas service before use on gas lines. Do not overtighten threaded joints; hand-tighten first and finish with a pipe wrench to avoid cracking fittings or distorting threads.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNipple Type\u003c\/strong\u003e: Close\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSchedule\u003c\/strong\u003e: Schedule 40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Welded steel, black oxide coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPT (standard pipe thread)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASTM A53\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.398 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: ASC Engineered Solutions\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8700144457\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51345858593074,"sku":"8700144457","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310547537.jpg?v=1782064839","url":"https:\/\/voomisupply.com\/products\/asc-engineered-solutions-8700144457-close-nipple-sch-40-black-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
