Machined from forged carbon steel with a black finish, this fitting is rated to Class 3000, making it suitable for demanding pressure applications up to 3000 psi. It features NPT end connections on both sides for threaded assembly into standard pipe runs. Plumbers, pipefitters, and mechanical contractors install this type of fitting when joining two sections of pipe or extending a threaded run in a compact, reliable connection.\u003c\/p\u003e\n\u003cp\u003eThis coupling is appropriate for use in gas and liquid piping systems where a Class 3000 forged fitting is specified. The 1\/4-inch size is commonly found in instrument lines, pilot gas lines, and small-diameter branch connections. NPT threads conform to standard tapered thread specifications, allowing compatibility with corresponding male-threaded pipe or fittings. The black finish is standard for carbon steel pipe fittings used in non-corrosive indoor environments and is commonly specified in gas distribution and mechanical piping assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass 3000 pressure rating — suitable for high-pressure gas and liquid service up to 3000 psi\u003c\/li\u003e\n  \u003cli\u003eForged carbon steel construction for strength and durability in demanding piping systems\u003c\/li\u003e\n  \u003cli\u003eBlack finish standard for carbon steel pipe fittings in mechanical and gas applications\u003c\/li\u003e\n  \u003cli\u003eNPT end connections on both sides for straightforward threaded assembly\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch fitting size for small-diameter piping and instrument connections\u003c\/li\u003e\n  \u003cli\u003eSold in a package quantity of 5 units per order\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-stock forged carbon steel coupling for use in 1\/4-inch NPT threaded 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 mechanical and gas piping codes, including IFGC and ASME B31 standards where applicable. Depressurize and isolate the piping system completely before disassembling or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape rated for the service medium to NPT threads before assembly. Do not overtighten — use a pipe wrench and follow standard NPT engagement practices to avoid thread damage or fitting failure.\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\/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 pieces\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: -12129-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694527217970,"sku":"-12129-1","price":32.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9e4343b59f2bb7763abd2b792c3f15d8.jpg?v=1788325086","url":"https:\/\/voomisupply.com\/products\/value-collection-12129-1-black-coupling-1-4-in-npt-class-3000","provider":"Voomi Supply","version":"1.0","type":"link"}
