It provides a three-way branch connection in threaded pipe systems rated at 150 lb working pressure. The nominal size is 3\/4 x 3\/4 x 1\/2 inches with female National Pipe Thread (FNPT) end connections on all three ports. Licensed plumbers and pipefitters install this fitting in gas distribution, hydronic heating, compressed air, and general industrial piping systems where a reliable, low-pressure branch takeoff is required.\u003c\/p\u003e\n\u003cp\u003eThis tee is suited for residential and light commercial piping applications. The reducing outlet — 1\/2 inch versus the 3\/4 inch run — allows a branch line to be stepped down without an additional bushing in many configurations. It is commonly installed in black iron gas piping, heating system supply and return lines, and shop air distribution. The FNPT thread pattern is the standard thread form used throughout North American pipe systems, ensuring broad interchangeability with pipe nipples, valves, and other fittings of matching size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMalleable iron construction provides strength and resistance to mechanical stress at threaded joints\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish suitable for black iron gas and steam piping applications\u003c\/li\u003e\n  \u003cli\u003e150 lb pressure rating covers the majority of residential and light commercial low-pressure service\u003c\/li\u003e\n  \u003cli\u003eFNPT threads on all three ports accept standard tapered pipe threads without adapters\u003c\/li\u003e\n  \u003cli\u003eReducing outlet (1\/2 inch) on branch port eliminates need for a separate reducing bushing in many installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-duty fitting for threaded malleable iron pipe systems using 3\/4 inch run pipe and a 1\/2 inch branch takeoff at 150 lb class service.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable local mechanical and plumbing codes, including IFGC requirements when used in gas service. Shut off and depressurize the line completely before disassembling any threaded connection. Apply an approved pipe thread sealant or PTFE tape to male threads before assembly — do not apply sealant to female ports. Hand-tighten first, then wrench-tighten to achieve a leak-free joint without over-stressing the casting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFigure Number\u003c\/strong\u003e: 3105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConfiguration\u003c\/strong\u003e: Straight Pipe Tee, Reducing Outlet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 3\/4 x 3\/4 x 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: FNPT (Female National Pipe Thread) all three ports\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 150 lb\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 Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrigin\u003c\/strong\u003e: Import\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: SIGMA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 810038208\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51525108236594,"sku":"BLTRED343412I-LF","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/76dfead0281cef7a6c3ed6387e524d84_0cc25dc3-a325-447d-bc5b-f4d1b254493f.jpg?v=1785464647","url":"https:\/\/voomisupply.com\/products\/sigma-810038208-malleable-iron-pipe-tee-3-4x3-4x1-2-in-150lb","provider":"Voomi Supply","version":"1.0","type":"link"}
