The fitting features a 1-inch run with 3\/4-inch branch and outlet connections, all threaded for standard NPT assembly. Manufactured from malleable iron with a black finish, it carries a Class 150 rating and is pressure-rated to 300 psi. This type of fitting is typically installed by licensed plumbers or gas fitters when transitioning between pipe sizes within a tee configuration on a distribution line.\u003c\/p\u003e\u003cp\u003eThis fitting is suited for residential and light commercial piping applications involving gas distribution, water supply, or other fluid systems where a threaded tee with a reducing outlet is required. The 1 x 3\/4 x 3\/4 inch configuration makes it a standard choice when stepping down from a 1-inch main line to 3\/4-inch branch and outlet runs. It ships as a single unit and is compatible with standard NPT threaded pipe and fittings of the same size classes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMalleable iron construction with black finish for durability in gas and liquid service\u003c\/li\u003e\n\u003cli\u003e1 x 3\/4 x 3\/4 inch tee reducer configuration for transitioning pipe sizes\u003c\/li\u003e\n\u003cli\u003eThreaded NPT end connections on all three ports\u003c\/li\u003e\n\u003cli\u003eClass 150 rated at 300 psi liquid and gas pressure\u003c\/li\u003e\n\u003cli\u003eSingle-piece unit, no additional hardware required for installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting compatible with standard NPT threaded malleable iron piping systems in Class 150 applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or gas fitter in accordance with applicable codes including the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC). Shut off the gas or water supply and relieve system pressure completely before making or breaking any threaded connections. Apply an approved thread sealant or PTFE tape to male threads before assembly. Do not overtighten threaded fittings, as malleable iron threads can crack under excessive force.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Tee Reducer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1 x 3\/4 x 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: Threaded (NPT)\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\u003eClassification\u003c\/strong\u003e: Class 150\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.4 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: BK MUELLER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 520-544HC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"B\u0026K MUELLER","offers":[{"title":"Default Title","offer_id":67916966101298,"sku":"520-544HC","price":24.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5ba741c091561b523ff38afde83d363c_305458c9-d198-4314-8bd4-e0cfb81c3eac.jpg?v=1791260369","url":"https:\/\/voomisupply.com\/products\/bk-mueller-520-544hc-black-iron-tee-reducer-1x3-4x3-4-threaded","provider":"Voomi Supply","version":"1.0","type":"link"}
