It connects two female-threaded fittings or ports with NPT threads on both ends and no unthreaded center length, which is the defining characteristic of a close nipple. The seamless tube eliminates weld seams, producing uniform wall strength and a smooth internal bore. Schedule 80 wall thickness provides greater pressure capacity and mechanical durability compared to Schedule 40. At 0.22 pounds, it is a compact, single-piece fitting suited to tight piping assemblies.\u003c\/p\u003e\n\u003cp\u003eThis nipple is appropriate for plumbing, industrial process, marine, chemical processing, and pharmaceutical piping systems where corrosion resistance is a primary concern. The 316 alloy adds molybdenum to the steel matrix, giving it stronger resistance to chlorides, acids, and pitting compared to 304 stainless. It is well suited to saltwater exposure, chemical transfer lines, steam service, and high-temperature fluid handling. Licensed plumbers and pipefitters are the primary installers, though mechanical contractors and industrial maintenance crews also install these fittings regularly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e316 stainless steel construction resists chlorides, acids, and pitting in corrosive environments\u003c\/li\u003e\n  \u003cli\u003eSeamless tube eliminates weld seams for uniform wall strength and consistent internal flow path\u003c\/li\u003e\n  \u003cli\u003eSchedule 80 wall thickness provides higher pressure ratings versus Schedule 40\u003c\/li\u003e\n  \u003cli\u003eNPT threads on both ends conform to ASME B1.20.1 for precise, leak-resistant connections\u003c\/li\u003e\n  \u003cli\u003eManufactured to ASTM A312\/SA312 material standards\u003c\/li\u003e\n  \u003cli\u003eFull lot code traceability included for quality assurance and compliance documentation\u003c\/li\u003e\n  \u003cli\u003ePressure tested at the factory to verify integrity under operating conditions\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 threaded piping systems requiring 316 stainless steel corrosion resistance and Schedule 80 wall thickness.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter following applicable IPC and ASME B31 piping codes. Isolate and depressurize the piping system completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape rated for the service fluid and temperature. Do not overtighten NPT threads, as stainless steel fittings are susceptible to galling if excessive torque or improper lubrication is used during assembly.\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\u003eNipple Type\u003c\/strong\u003e: Close\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 316 Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSchedule\u003c\/strong\u003e: 80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: Seamless\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPT both ends\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: ASME B1.20.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Standard\u003c\/strong\u003e: ASTM A312\/SA312\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.22 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 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: MSI PRODUCTS INC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A3970016C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MSI PRODUCTS INC","offers":[{"title":"Default Title","offer_id":68060813263154,"sku":"A3970016C","price":24.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0dd017d162678e3dd32a7fe3e7e43111_92bb506c-81fe-4a9f-98fb-68f64a8c880a.jpg?v=1793038359","url":"https:\/\/voomisupply.com\/products\/msi-products-inc-a3970016c-316-ss-close-nipple-sch-80","provider":"Voomi Supply","version":"1.0","type":"link"}
