This fitting features a 1-inch nominal size with female national pipe taper (FNPT) end connections on all three ports. Constructed from malleable iron with a galvanized finish, it carries a 150 lb pressure class rating. The galvanized coating provides corrosion resistance in wet and exposed environments. Licensed plumbers and pipefitters install this type of fitting when branching a run of threaded pipe in domestic water, gas distribution, compressed air, or hydronic heating applications.\u003c\/p\u003e\n\u003cp\u003eThis straight tee is suited for residential and light commercial piping installations where a branch takeoff is needed at the same nominal pipe size as the main run. The FNPT threads on all outlets accept standard NPT male-threaded pipe or fittings. Typical applications include water supply lines, low-pressure gas piping, steam systems rated within the 150 lb class, and compressed air distribution headers. The galvanized malleable iron construction makes it appropriate for exposed or semi-exposed installations where raw black iron would be susceptible to surface rust.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-inch nominal size with FNPT connections on all three ports\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 environments\u003c\/li\u003e\n  \u003cli\u003eStraight tee configuration — branch and run at equal nominal size\u003c\/li\u003e\n  \u003cli\u003eFIG 3105 pattern fitting for standard threaded pipe systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard trade fitting for 1-inch nominal threaded pipe systems using NPT connections rated at 150 lb class.\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 codes such as the IPC or IFGC depending on the fluid service. Shut off and depressurize the pipe system completely before disassembling any threaded connections. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly, and tighten to a snug fit using pipe wrenches — do not overtighten malleable iron fittings. Inspect the galvanized threads for damage before installation to ensure a leak-free seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: FNPT (Female National Pipe Taper)\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 3105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConfiguration\u003c\/strong\u003e: Straight Tee\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: 811030212\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51524776001842,"sku":"GALT1I-LF","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2b54741e388311a86c0c5910331119d8_36f55f87-e2be-4d04-b9ea-fefeaf4be147.jpg?v=1785457203","url":"https:\/\/voomisupply.com\/products\/sigma-811030212-fig-3105-straight-pipe-tee-1-in-fnpt-150-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
