Sized at 3\/8 inches on each port and rated Class 150, this fitting is built for use in low-pressure piping systems carrying natural gas, LP gas, steam, lubricant oil, grease, or diesel fuel. The black finish is standard for malleable iron gas and steam pipe fittings. Plumbers, pipefitters, and HVAC technicians install this type of fitting when branching a run of threaded pipe into two directions without changing direction or reducing size.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for residential and light commercial piping installations where a consistent 3\/8-inch threaded branch is required. Common applications include gas supply lines, steam distribution systems, oil lubrication lines, and diesel fuel piping. All three FPT connections accept standard NPT male-threaded pipe, making it compatible with typical black iron pipe systems used throughout HVAC, plumbing, and industrial service work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStraight tee configuration with equal 3\/8-inch FPT ports on all three connections\u003c\/li\u003e\n  \u003cli\u003eClass 150 pressure rating suitable for low-pressure gas, steam, and fluid service\u003c\/li\u003e\n  \u003cli\u003eMalleable iron construction for strength and resistance to mechanical stress\u003c\/li\u003e\n  \u003cli\u003eBlack finish standard for gas and steam pipe fittings\u003c\/li\u003e\n  \u003cli\u003eRated for natural gas, LP gas, steam, lubricant oil, grease, and diesel applications\u003c\/li\u003e\n  \u003cli\u003eNPT-compatible female threads on all three ports for standard black iron pipe\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 150 malleable iron threaded piping systems using standard 3\/8-inch NPT connections in gas, steam, oil, and fuel service.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable codes such as the IFGC for gas systems or ASME B31 for piping. Shut off and isolate the supply line and verify zero pressure before disassembling or connecting any threaded fittings. Apply an appropriate pipe thread sealant or PTFE tape rated for the service medium to all male threads before assembly. Do not overtighten; use a pipe wrench with backup on adjacent fittings to avoid stressing the system.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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: Female Threaded x Female Threaded x Female Threaded (FPT)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 3\/8 inches x 3\/8 inches x 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: Class 150\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConfiguration\u003c\/strong\u003e: Straight Tee\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Natural Gas, LP Gas, Steam, Lubricant Oil, Grease, Diesel\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: MUELLER INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 520-602\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER INDUSTRIES","offers":[{"title":"Default Title","offer_id":51284102742322,"sku":"520-602","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277707.jpg?v=1781068593","url":"https:\/\/voomisupply.com\/products\/mueller-industries-520-602-malleable-iron-tee-3-8-fpt","provider":"Voomi Supply","version":"1.0","type":"link"}
