Manufactured from welded steel with a black coating applied to resist corrosion, this nipple measures 3\/8 inch nominal diameter by 4 inches in length and is built to Schedule 40 wall thickness. Standard NPT threads on both ends allow direct connection to fittings, valves, and other threaded components. Licensed plumbers and pipefitters install this type of nipple as a close-tolerance spacer or extension in low-pressure fluid and gas piping runs. It meets ASTM A53 standards for steel pipe, confirming consistent dimensional and mechanical properties.\u003c\/p\u003e\n\u003cp\u003eThis nipple is suited for residential and light commercial applications including natural gas and propane distribution lines, steam and hot water heating systems, compressed air lines, and general-purpose black iron piping assemblies. Its Schedule 40 wall thickness makes it appropriate for standard-pressure service in these systems. It is sold individually and installs wherever a short, threaded steel extension or riser is required between two pipe fittings or threaded components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSchedule 40 wall thickness for standard-pressure service\u003c\/li\u003e\n  \u003cli\u003eBlack coating resists corrosion during storage and service\u003c\/li\u003e\n  \u003cli\u003eStandard NPT threads on both ends for compatibility with threaded fittings and valves\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM A53 standards for welded steel pipe\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch nominal diameter by 4 inches in length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation component for standard 3\/8 inch NPT threaded black iron piping systems used in gas, steam, hot water, and compressed air applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber or pipefitter following applicable local codes and IFGC or IPC requirements depending on the fluid service. Shut off gas or water supply and depressurize the line before disassembling or adding any threaded connection. Apply an appropriate thread sealant or PTFE tape rated for the specific service medium before making up connections. Do not over-torque threaded joints, as this can crack fittings or damage thread integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Pipe Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4 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: 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: 0.178 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: 8700137808\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51347995361586,"sku":"8700137808","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310547477.jpg?v=1782117378","url":"https:\/\/voomisupply.com\/products\/asc-engineered-solutions-8700137808-black-iron-nipple-3-8x4-in-sch-40","provider":"Voomi Supply","version":"1.0","type":"link"}
