It is used to join two sections of threaded pipe in pressurized piping systems. The 1-1\/4 inch fitting size suits mid-range pipeline diameters common in commercial and industrial installations. This coupling carries multiple third-party certifications, including FM Approval and cULus Listing, making it suitable for fire protection, plumbing, and mechanical piping applications. Licensed plumbers, pipefitters, and mechanical contractors are the typical installers. The Class 300 pressure rating supports higher-pressure service beyond standard Class 150 fittings.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for use in commercial and industrial piping systems where threaded malleable iron fittings are specified. Typical applications include fire suppression lines, steam distribution, compressed air headers, and general mechanical piping. The black finish is standard for gas and fire protection piping where galvanized fittings are not required or permitted. The 1-1\/4 inch nominal size fits within common branch and main line configurations in mid-size mechanical systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass 300 pressure rating for higher-pressure piping service\u003c\/li\u003e\n  \u003cli\u003eMalleable iron construction for strength and thread integrity\u003c\/li\u003e\n  \u003cli\u003eBlack finish standard for gas and fire protection piping\u003c\/li\u003e\n  \u003cli\u003eThreaded connection type for field assembly without welding or grooved tools\u003c\/li\u003e\n  \u003cli\u003eFM Approved and cULus Listed for use in fire protection and listed mechanical applications\u003c\/li\u003e\n  \u003cli\u003eMeets ABNT, EN 10242, GB\/T 3287, GB\/T 7306.2, and ISO 7\/1 standards\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 Class 300 threaded malleable iron piping systems with 1-1\/4 inch nominal pipe connections.\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 local mechanical codes and IFGC or IPC requirements where relevant. Depressurize and isolate the piping system completely before removing or installing any threaded fittings. Apply an approved thread sealant or PTFE tape to the male threads before assembly and tighten to manufacturer and code-specified engagement. Do not over-torque malleable iron fittings, as the material can crack under excessive force.\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: 1-1\/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\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Class\u003c\/strong\u003e: Class 300\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ABNT Certified, EN 10242, FM Approved, GB\/T 3287, GB\/T 7306.2, ISO 7\/1, cULus Listed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 2\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: MDB220 32-2 300#\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700935983410,"sku":"MDB220 32-2 300#","price":22.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ce352564dabd670f8d45fad61eab4b9b.jpg?v=1788395536","url":"https:\/\/voomisupply.com\/products\/value-collection-mdb220-32-2-300-threaded-coupling-1-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
