A close nipple has threads running nearly the full length of the fitting with minimal or no unthreaded center section, making it the right choice when two fittings need to be joined with the shortest possible pipe segment. The black coating provides baseline corrosion resistance for dry or low-moisture environments. Standard NPT threads ensure a reliable, leak-resistant connection when assembled with compatible fittings and appropriate thread sealant. Licensed plumbers and pipefitters install this fitting in gas, steam, air, and water distribution systems.\u003c\/p\u003e\n\u003cp\u003eThis close nipple is used in residential and light commercial piping applications where a 1-inch threaded connection is required with minimal standoff between fittings. Typical installations include natural gas supply lines, steam heating systems, compressed air distribution, and black iron water supply runs. The Schedule 40 wall thickness meets standard pressure requirements for these service types. It is sold individually and is a common stock item for plumbers, pipefitters, and mechanical contractors working on both new construction and service replacement projects.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSchedule 40 wall thickness rated for standard pressure service in gas, steam, air, and water lines\u003c\/li\u003e\n  \u003cli\u003eBlack iron coating helps resist surface corrosion in dry to low-moisture environments\u003c\/li\u003e\n  \u003cli\u003eClose configuration minimizes installed length between two threaded fittings\u003c\/li\u003e\n  \u003cli\u003eStandard NPT threads are compatible with standard pipe fittings and valves\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM A53 requirements for welded steel pipe\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 1-inch NPT Schedule 40 black iron threaded piping systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable local mechanical and plumbing codes. Shut off and depressurize the line completely before making or breaking any threaded connection. Apply an appropriate thread sealant or PTFE tape to male threads before assembly and tighten to a snug, leak-free fit using pipe wrenches. Do not overtighten, as this can crack fittings or distort threads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConfiguration\u003c\/strong\u003e: Close nipple\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 iron coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Standard NPT\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: 0.136 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\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: ASC Engineered Solutions\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8700140851\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51344049045810,"sku":"8700140851","price":19.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310547465.jpg?v=1782027806","url":"https:\/\/voomisupply.com\/products\/asc-engineered-solutions-8700140851-black-iron-close-nipple","provider":"Voomi Supply","version":"1.0","type":"link"}
