A close nipple is threaded along its entire length with no unthreaded center, making it the correct choice when two fittings must be joined with minimal gap between them. This nipple measures 4 inches in diameter and 2-7\/8 inches in length, placing it in the heavy-duty size range used in industrial and commercial piping runs. Licensed plumbers and pipefitters install this type of nipple in gas, water, and steam distribution systems where a compact, rigid connection is required.\u003c\/p\u003e\u003cp\u003eThis close nipple is suited for residential and commercial plumbing, HVAC hydronic systems, and industrial pipe assemblies where Schedule 40 wall thickness is specified. It is used wherever a full-length threaded nipple is needed to connect two female-threaded fittings directly, such as unions, couplings, valves, and manifolds. The black steel construction makes it a common choice for natural gas and propane supply lines as well as fire suppression headers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClose nipple design — fully threaded along entire body length for tight back-to-back fitting connections\u003c\/li\u003e\n\u003cli\u003eSchedule 40 wall thickness provides pressure-rated durability for gas, water, and steam service\u003c\/li\u003e\n\u003cli\u003eBlack steel construction suitable for gas distribution and hydronic piping applications\u003c\/li\u003e\n\u003cli\u003eThreads conform to ANSI\/ASME B1.20.1 standard for interchangeable NPT fitment\u003c\/li\u003e\n\u003cli\u003eASTM-referenced material standard for consistent steel quality\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation component compatible with standard NPT female-threaded fittings and valves in Schedule 40 black steel piping systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and IFGC requirements. Shut off and depressurize the line before removing or installing any threaded nipple. Apply an approved thread sealant or PTFE tape to the male threads before makeup, and tighten with pipe wrenches to achieve a proper pressure-tight joint. Do not over-torque close nipples, as the short body provides limited engagement length on each end.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNipple Type\u003c\/strong\u003e: Close\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2-7\/8 inches\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: Black Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: ANSI\/ASME B1.20.1 NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Standard\u003c\/strong\u003e: ASTM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: NB13001\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721946202418,"sku":"NB13001","price":23.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/07572f533977876f3691e4cf3a63d901.jpg?v=1788583594","url":"https:\/\/voomisupply.com\/products\/value-collection-nb13001-close-pipe-nipple-4-in-sch-40-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
