The reducing tee connects a 1-inch run to 3\/4-inch branch and outlet connections, making it a standard fitting for residential and light commercial piping configurations. The black oxide finish provides a basic level of corrosion resistance suited for dry or semi-dry interior installations. Plumbers and pipefitters install this fitting as part of threaded iron pipe assemblies where a change in line size or a branch takeoff is required.\u003c\/p\u003e\n\u003cp\u003eThis tee is used in residential and commercial plumbing, gas piping, and steam or air distribution systems where malleable iron threaded fittings are specified. The 150 lb pressure rating covers typical service conditions in low- to medium-pressure pipe systems. It is commonly installed in boiler rooms, mechanical rooms, and utility piping runs where NPT-threaded black iron pipe is standard practice.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReducing tee configuration: 1 inch run by 3\/4 inch by 3\/4 inch branch and outlet\u003c\/li\u003e\n  \u003cli\u003e150 lb pressure rating for low- to medium-pressure service\u003c\/li\u003e\n  \u003cli\u003eMalleable iron construction for strength and machinability at threaded joints\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish suitable for interior gas, air, and water piping applications\u003c\/li\u003e\n  \u003cli\u003eNPT-threaded connections compatible with 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 150 lb malleable iron threaded pipe systems using NPT connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter following applicable IPC or IFGC code requirements. Shut off and depressurize the pipe system completely before removing or installing any threaded fittings. Apply listed pipe thread sealant or PTFE tape to male threads before assembly, and tighten to a proper thread engagement without over-torquing, which can crack malleable iron. Do not use this fitting in systems that exceed its rated pressure or temperature limits.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Reducing Tee\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1 x 3\/4 x 3\/4 inches\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\u003eConnection Type\u003c\/strong\u003e: NPT Threaded\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: 810040808\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51524687298866,"sku":"BLTRED13434I-LF","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/76dfead0281cef7a6c3ed6387e524d84_37ba5a21-b30b-4042-8d61-98c996821661.jpg?v=1785455263","url":"https:\/\/voomisupply.com\/products\/sigma-810040808-malleable-iron-pipe-tee-1x3-4x3-4-in-150-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
