Machined from forged carbon steel with a black finish, this coupling carries a Class 3000 pressure rating of 3000 psi, making it suitable for demanding liquid and gas service. Female NPT threads on both ends allow direct inline connection of same-diameter pipe sections. Licensed plumbers, pipefitters, and mechanical contractors specify this fitting where strength and pressure integrity are required.\u003c\/p\u003e\n\u003cp\u003eThis coupling is used in industrial process piping, steam lines, compressed air systems, hydraulic lines, and general liquid or gas distribution wherever threaded forged steel fittings are required. Its Class 3000 rating suits high-pressure applications beyond the range of standard malleable iron fittings. Sold in a package quantity of 5 units, it is well suited for contractors needing multiple fittings per job.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eForged carbon steel construction for high strength and pressure integrity\u003c\/li\u003e\n  \u003cli\u003eClass 3000 rating at 3000 psi for demanding liquid and gas service\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch NPT female threads on both ends for standard inline pipe joining\u003c\/li\u003e\n  \u003cli\u003eBlack finish provides a consistent appearance for industrial installations\u003c\/li\u003e\n  \u003cli\u003eSold in a package of 5 units for efficient job-site stocking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style threaded replacement fitting for 3\/4-inch NPT forged carbon steel piping systems rated to Class 3000 service in industrial and commercial installations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber or pipefitter following applicable IFGC, IPC, or local mechanical code requirements. De-pressurize and isolate the line completely before disassembly or fitting installation. Apply appropriate thread sealant or PTFE tape to NPT threads per code and system media requirements. Do not over-torque threaded joints; tighten to achieve a leak-free seal without stressing the fitting body.\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: 3\/4 inches\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\u003eLiquid and Gas Pressure 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\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40175303\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: -12129-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717066621234,"sku":"-12129-4","price":34.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d9331ebe85bec8e8ff1851bb62ee0968.jpg?v=1788535255","url":"https:\/\/voomisupply.com\/products\/value-collection-12129-4-black-coupling-3-4-in-npt-class-3000","provider":"Voomi Supply","version":"1.0","type":"link"}
