Sized at 1 inch with NPT end connections, this coupling is rated to Class 3000 and carries a 3000 psi pressure rating, making it suitable for demanding liquid and gas service. The black finish is a standard mill-applied coating typical of carbon steel fittings. Licensed plumbers, pipefitters, and industrial maintenance technicians are the primary installers of this type of fitting. This listing includes a package quantity of five couplings per order.\u003c\/p\u003e\n\u003cp\u003eThis coupling is used in high-pressure threaded piping assemblies where forged carbon steel construction is required. Common applications include steam lines, compressed air systems, hydraulic lines, and gas distribution piping in commercial and industrial facilities. The Class 3000 rating aligns with ASME B16.11 standards for forged fittings, making this coupling appropriate for systems that demand reliable pressure containment at 1-inch connection points. It is not intended for use with stainless or corrosive-media systems where carbon steel is unsuitable.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eForged carbon steel construction provides strength for high-pressure service\u003c\/li\u003e\n  \u003cli\u003eClass 3000 rating with 3000 psi pressure capacity for liquid and gas applications\u003c\/li\u003e\n  \u003cli\u003e1-inch NPT end connections for standard threaded pipe assembly\u003c\/li\u003e\n  \u003cli\u003eBlack mill finish typical of carbon steel pipe fittings\u003c\/li\u003e\n  \u003cli\u003eSold in a convenient 5-pack quantity per package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style threaded coupling for use in 1-inch NPT high-pressure carbon steel piping systems rated to Class 3000 service conditions.\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 codes such as the International Plumbing Code or ASME B31.3 for process piping. Isolate and fully depressurize the piping system before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to NPT threads per manufacturer and code guidance. Do not overtighten threaded connections, as this can damage threads or crack fittings.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Coupling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Forged Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClassification\u003c\/strong\u003e: Class 3000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 3000 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40175303\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: -12129-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716604199218,"sku":"-12129-5","price":55.81,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/41818564570e668213531528b208798b.jpg?v=1788528744","url":"https:\/\/voomisupply.com\/products\/value-collection-12129-5-black-coupling-1-inch-npt-class-3000","provider":"Voomi Supply","version":"1.0","type":"link"}
