Manufactured from welded steel with a black iron coating, it meets ASTM A53 standards for structural and pressure service. The close-length configuration positions two threaded ends with minimal exposed barrel, making it the right choice when a standard-length nipple would create unwanted spacing in a fitting-to-fitting connection. Licensed plumbers and pipefitters install this nipple wherever a tight inline connection is required between two threaded fittings.\u003c\/p\u003e\n\u003cp\u003eThis nipple is suited for residential and light commercial plumbing, gas distribution, and hydronic heating applications. Its Schedule 40 wall thickness handles standard system pressures across a range of pipe uses. The close configuration is especially common in gas piping manifolds, boiler trim piping, and compressed air headers where back-to-back fittings need a secure, rigid metal-to-metal transition without extra standoff length.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClose-length configuration for fitting-to-fitting connections with minimal exposed pipe\u003c\/li\u003e\n  \u003cli\u003eBlack iron coating provides corrosion resistance for interior and protected installations\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM A53 standards for welded steel pipe in pressure and structural service\u003c\/li\u003e\n  \u003cli\u003eSchedule 40 wall thickness for standard working pressures\u003c\/li\u003e\n  \u003cli\u003eStandard NPT threads for compatibility with common threaded pipe fittings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-stock close nipple for 3\/4 inch Schedule 40 threaded pipe systems using NPT fittings in plumbing, gas, or hydronic applications.\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 codes and the International Fuel Gas Code or International Plumbing Code where relevant. Apply an approved thread sealant or PTFE tape rated for the service medium before making up threaded joints. Tighten to a snug, wrench-tight fit using a pipe wrench — do not overtighten, as this can crack adjacent cast fittings. Pressure-test the assembly before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNipple Pattern\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Iron Coating\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: 0.095 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: 8700139606\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51345826709810,"sku":"8700139606","price":20.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310547447.jpg?v=1782064006","url":"https:\/\/voomisupply.com\/products\/asc-engineered-solutions-8700139606-black-iron-close-nipple","provider":"Voomi Supply","version":"1.0","type":"link"}
