Rated as extra heavy (XH), this fitting provides greater wall thickness and strength compared to standard malleable iron couplings, making it suitable for higher-pressure and more demanding service conditions. The black finish results from an oil coating applied after the casting process, which is standard for malleable iron pipe fittings used in gas, air, and industrial piping applications. Licensed plumbers and pipefitters typically specify extra heavy malleable iron fittings where elevated pressure ratings or mechanical durability are required.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is used in threaded pipe assemblies where a 1-1\/2 inch line must transition down to a 3\/4 inch line. Common applications include natural gas distribution piping, compressed air systems, steam systems, and industrial fluid handling. It is installed in both commercial and light industrial settings wherever a Schedule 40 or heavier threaded steel or iron pipe system requires a concentric diameter reduction at a coupling joint.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExtra heavy (XH) wall construction for increased pressure capability and mechanical strength\u003c\/li\u003e\n  \u003cli\u003eExtra heavy malleable iron material provides toughness and resistance to cracking under stress\u003c\/li\u003e\n  \u003cli\u003eBlack oil finish standard for gas, air, and industrial piping service\u003c\/li\u003e\n  \u003cli\u003eReduces from 1-1\/2 inch to 3\/4 inch in a single threaded fitting\u003c\/li\u003e\n  \u003cli\u003eNPT female threads on both ends for standard threaded pipe connections\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 extra heavy threaded malleable iron piping systems requiring a 1-1\/2 inch to 3\/4 inch concentric reduction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber or pipefitter following applicable code requirements such as IFGC or ASME B16.3 for malleable iron fittings. Shut off and depressurize the piping system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape rated for the service medium to all male threads before assembly. Do not over-tighten threaded joints; follow standard trade practice for thread engagement on NPT connections.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Extra Heavy Malleable Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.38 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: BMI USA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 20037\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BMI USA","offers":[{"title":"Default Title","offer_id":51347227541810,"sku":"20037","price":43.68,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310553992.jpg?v=1782099634","url":"https:\/\/voomisupply.com\/products\/bmi-usa-20037-black-iron-reducer-coupling-1-1-2-x-3-4-inch-xh","provider":"Voomi Supply","version":"1.0","type":"link"}
