Finished in black and rated at Class 125, this fitting joins three pipe runs while reducing one outlet from 1 inch to 3\/4 inch, making it a practical choice wherever branch line sizing changes are required. All three connections are female NPT threaded, conforming to ASME B1.20.1 thread standards. The fitting meets ASME B16.3 and ASTM A-197 material standards and carries FM Approval and cULus Listing, meeting the certification requirements common in fire protection and mechanical system specifications.\u003c\/p\u003e\u003cp\u003eThis reducing tee is suited for low-pressure gas and liquid distribution lines in residential, commercial, and light industrial applications. Typical installations include natural gas branch lines, compressed air networks, and water distribution headers where a tee with a reduced branch outlet is needed. The Class 125 pressure rating and cast iron construction make it appropriate for use in both above-ground and exposed mechanical room piping where code-compliant fittings are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCast iron construction with black finish for corrosion resistance in standard service environments\u003c\/li\u003e\n\u003cli\u003eClass 125 rated at 125 psi for liquid and gas service\u003c\/li\u003e\n\u003cli\u003eAll female NPT threaded connections per ASME B1.20.1\u003c\/li\u003e\n\u003cli\u003eReducing branch outlet: 1 x 3\/4 x 1 inch configuration\u003c\/li\u003e\n\u003cli\u003eMeets ASME B16.3 and ASTM A-197 standards\u003c\/li\u003e\n\u003cli\u003eFM Approved and cULus Listed for use in code-governed installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Class 125 cast iron threaded reducing tee compatible with NPT-threaded pipe in 1 inch run and 3\/4 inch branch configurations across gas and liquid distribution systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical codes such as the IPC or IFGC. Shut off and depressurize the line before disassembly or fitting installation. Apply an approved pipe thread sealant or PTFE tape to male threads before assembly. Do not over-tighten threaded connections in cast iron fittings, as the material is not tolerant of the same torque as malleable iron.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Reducing Tee\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1 x 3\/4 x 1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: Female NPT Threaded (FPT)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT per ASME B1.20.1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast 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 125\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 125 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B1.20.1, ASME B16.3, ASTM A-197, FM Approved, cULus Listed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.94 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.94 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.94 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.13 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: ANVIL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 0300037603\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51689097560370,"sku":"0300037603","price":23.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d9a82b04428fe135760bb7a2b638c2f6_b498ea95-9958-42c7-9f84-9d25131db950.jpg?v=1788254695","url":"https:\/\/voomisupply.com\/products\/anvil-0300037603-cast-iron-reducing-tee-1x3-4x1-threaded","provider":"Voomi Supply","version":"1.0","type":"link"}
