Manufactured from malleable iron with a galvanized finish, this fitting handles a 150 lb pressure class and connects three pipe runs in a reducing configuration. The nominal size is 1-1\/4 x 1 x 1\/2 inches, with female National Pipe Taper (FNPT) threads on all three ends. The galvanized coating provides corrosion resistance in wet or exposed service conditions. Licensed plumbers and pipefitters install this fitting in low-pressure water, air, and gas distribution lines where a branch takeoff at a reduced size is required.\u003c\/p\u003e\u003cp\u003eThis reducing tee is suited for residential and light commercial piping where a main run steps down or branches off to a smaller diameter line. Typical applications include water distribution headers, compressed air systems, and gas supply rough-in work. The FNPT thread pattern is the standard in North American threaded pipe systems, making this fitting compatible with standard Schedule 40 and Schedule 80 threaded pipe of the corresponding nominal sizes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eReducing configuration: 1-1\/4 inch run x 1 inch run x 1\/2 inch branch\u003c\/li\u003e\n\u003cli\u003eFNPT threads on all three ends for standard threaded pipe assembly\u003c\/li\u003e\n\u003cli\u003e150 lb pressure class malleable iron construction\u003c\/li\u003e\n\u003cli\u003eGalvanized finish for corrosion resistance in wet or exposed service\u003c\/li\u003e\n\u003cli\u003eFIG 3105R pattern — a widely recognized standard fitting configuration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-service reducing tee for threaded malleable iron piping systems rated at 150 lb class, compatible with nominal 1-1\/4 inch, 1 inch, and 1\/2 inch FNPT threaded pipe.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC requirements. Shut off and depressurize the system completely before disassembling any threaded connections. Apply an approved pipe thread sealant or PTFE tape to the male threads before assembly — do not apply sealant to female threads. Hand-tighten first, then use a pipe wrench to achieve a proper pressure-tight connection without over-torquing the fitting body.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1-1\/4 x 1 x 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: FNPT (Female National Pipe Taper) all ends\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Class\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: Galvanized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFigure Number\u003c\/strong\u003e: FIG 3105R\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 811043819\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51524262297906,"sku":"GALTRED114112I-LF","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/76dfead0281cef7a6c3ed6387e524d84_57f2e0bf-9986-4413-87d5-c4179d1d4614.jpg?v=1785445587","url":"https:\/\/voomisupply.com\/products\/sigma-811043819-malleable-iron-reducing-tee-1-1-4x1x1-2-fnpt-150lb","provider":"Voomi Supply","version":"1.0","type":"link"}
