This fitting transitions a 1-inch pipe connection down to a 3\/4-inch connection using tapered threads that conform to GB\/T 7306.2 and ISO 7\/1 standards. The Class 150 pressure rating makes it suitable for low- and medium-pressure service lines. Each package contains 5 couplings. Licensed plumbers and pipefitters are the primary installers for this type of fitting in both new construction and retrofit work.\u003c\/p\u003e\u003cp\u003eThis reducing coupling is used in residential and light commercial piping systems where a pipe diameter reduction is needed in a straight run. Typical applications include natural gas supply lines, water distribution, steam, and air piping within Class 150 service parameters. The threaded connection style allows installation without welding or soldering, making field assembly straightforward. The black finish is standard for gas-service malleable iron fittings and is widely specified in mechanical rooms, utility spaces, and exposed pipe runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eReduces from 1-inch to 3\/4-inch in a single threaded fitting\u003c\/li\u003e\n\u003cli\u003eMalleable iron construction provides strength and thread integrity under pressure cycling\u003c\/li\u003e\n\u003cli\u003eBlack finish — standard for gas-service piping installations\u003c\/li\u003e\n\u003cli\u003eThreaded connection type — no welding or soldering required\u003c\/li\u003e\n\u003cli\u003eClass 150 pressure rating — suitable for low- to medium-pressure systems\u003c\/li\u003e\n\u003cli\u003eConforms to GB\/T 7306.2 and ISO 7\/1 threading standards\u003c\/li\u003e\n\u003cli\u003eSold in a 5-pack for job-site efficiency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for threaded malleable iron pipe systems rated at Class 150, using 1-inch to 3\/4-inch pipe connections.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable local mechanical codes and IFGC requirements for gas-service piping. Shut off all gas or water supply and depressurize the line before removing or installing any threaded fittings. Apply appropriate thread sealant or PTFE tape to male threads before assembly. Do not over-torque threaded malleable iron fittings, as this can crack the fitting body or damage thread engagement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Reducing Coupling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1 x 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\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 150\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: GB\/T 7306.2, ISO 7\/1\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\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: MDB240 25X20-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720327168306,"sku":"MDB240 25X20-5","price":48.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f26099286386eb419f0b21ef7fabfd7b.jpg?v=1788562490","url":"https:\/\/voomisupply.com\/products\/value-collection-mdb240-25x20-5-reducing-coupling-5-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
