Manufactured from welded steel with a black coating applied to resist corrosion, it conforms to ASTM A53 standards for structural and pressure pipe. The close pattern means the nipple has no unthreaded center section — threads run the full length, making it the right choice when minimal spacing between fittings is required. Plumbers, pipefitters, and gas technicians install these nipples as part of assembled piping runs in both residential and light commercial applications.\u003c\/p\u003e\n\u003cp\u003eThis close nipple is suited for threaded pipe assemblies where space between fittings is tight or where a direct coupling connection is needed. Common install scenarios include gas supply lines, boiler piping, steam distribution, and general water service piping. The standard NPT thread profile mates with Schedule 40 fittings, valves, and couplings across a wide range of brands and configurations. Minimum order quantity is 6 pieces per order unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClose pattern — fully threaded with no bare center, minimizes fitting-to-fitting distance\u003c\/li\u003e\n  \u003cli\u003eSchedule 40 wall thickness rated for standard pressure service\u003c\/li\u003e\n  \u003cli\u003eBlack steel coating provides corrosion resistance over bare pipe\u003c\/li\u003e\n  \u003cli\u003eConforms to ASTM A53 welded steel pipe standard\u003c\/li\u003e\n  \u003cli\u003eStandard NPT thread for broad fitting compatibility\u003c\/li\u003e\n  \u003cli\u003eSold individually, minimum quantity of 6 units per order\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard NPT-threaded Schedule 40 black iron nipple for use with compatible Schedule 40 pipe fittings, valves, and couplings in gas, steam, and water piping systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or pipefitters following applicable local codes and the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) as appropriate for the service. Apply a listed pipe thread sealant or PTFE tape rated for the intended service — gas, steam, or water — before threading the nipple into fittings. Shut off and depressurize the system completely before disturbing any existing connections. Do not over-tighten threaded joints; wrench-tighten to achieve a leak-free seal without stressing the fitting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePattern\u003c\/strong\u003e: Close\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSchedule\u003c\/strong\u003e: 40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Welded steel, black 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: 0.031 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each (minimum quantity 6)\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: 8700136750\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51344789111090,"sku":"8700136750","price":19.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310547434.jpg?v=1782043741","url":"https:\/\/voomisupply.com\/products\/asc-engineered-solutions-8700136750-black-iron-close-nipple","provider":"Voomi Supply","version":"1.0","type":"link"}
