This Class 150 fitting carries a pressure rating of 300 psi for liquid and gas service and 150 psi for steam service, making it suited for a wide range of fluid and gas distribution applications. The galvanized finish provides corrosion resistance in exposed or moderately harsh environments. Licensed plumbers, pipefitters, and mechanical contractors reach for this coupling when joining two lengths of threaded pipe in-line without changing direction or size.\u003c\/p\u003e\u003cp\u003eThis coupling is used in residential and light commercial piping installations where standard 3\/4 inch threaded connections are required. Common applications include natural gas distribution lines, compressed air systems, hydronic heating supply and return lines, and general water service piping. The malleable iron construction and galvanized finish make it appropriate for above-ground interior installations as well as applications where moderate corrosion resistance is needed. It conforms to ISO 7\/1 threading standards, ensuring compatibility with standard NPT and ISO-threaded pipe and fittings in the same size.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e300 psi pressure rating for liquid and gas service\u003c\/li\u003e\n\u003cli\u003e150 psi pressure rating for steam service\u003c\/li\u003e\n\u003cli\u003eMalleable iron construction for durability in threaded piping systems\u003c\/li\u003e\n\u003cli\u003eGalvanized finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eThreaded end connections conforming to ISO 7\/1 standards\u003c\/li\u003e\n\u003cli\u003eClass 150 fitting designation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-service fitting for 3\/4 inch threaded malleable iron piping systems conforming to ISO 7\/1 threading standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter following applicable local mechanical and plumbing codes. Shut off and depressurize the piping system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to male threads before assembly, and tighten to hand-tight plus wrench-tight using a pipe wrench — do not overtighten malleable iron fittings as this can crack the casting. For gas service installations, verify connections with an approved leak detection method before returning the system to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eMaterial\u003c\/strong\u003e: Malleable Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Galvanized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLiquid and Gas Pressure Rating\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSteam Pressure Rating\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass\u003c\/strong\u003e: 150\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 7\/1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.33 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: G220 20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723021877554,"sku":"G220 20","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/31aae36dea6498b0cad45d7bf445230f.jpg?v=1788599390","url":"https:\/\/voomisupply.com\/products\/value-collection-g220-20-malleable-iron-pipe-coupling-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
