Built to FIG 3105 standards, this tee features a 1-1\/2 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 rating. The galvanized coating provides corrosion resistance for installations in wet or exposed environments. Licensed plumbers and pipefitters install this fitting in both new construction and retrofit applications.\u003c\/p\u003e\n\u003cp\u003eThis tee is suited for residential and light commercial piping systems where a branch connection is required along a straight run of threaded pipe. Common applications include water supply lines, gas distribution piping, compressed air systems, and steam lines operating within the 150 lb pressure class. The FNPT threading on all three outlets ensures compatibility with standard NPT male-threaded pipe and fittings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/2 inch nominal size with FNPT connections on all three ports\u003c\/li\u003e\n  \u003cli\u003e150 lb pressure-rated malleable iron construction\u003c\/li\u003e\n  \u003cli\u003eGalvanized finish for corrosion resistance in wet or exposed environments\u003c\/li\u003e\n  \u003cli\u003eFIG 3105 straight tee configuration for in-line branch connections\u003c\/li\u003e\n  \u003cli\u003eStandard NPT threading for wide compatibility with 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 fitting for 1-1\/2 inch nominal threaded pipe systems using 150 lb class malleable iron fittings with NPT connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC guidelines. Shut off and depressurize the line before disassembly or installation. Apply an appropriate thread sealant or PTFE tape to all male NPT threads before assembly and tighten to a snug, leak-free fit using pipe wrenches. Do not over-torque malleable iron fittings, as the material can crack under excessive force.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1-1\/2 inches\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 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: 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: 811030618\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51524563403058,"sku":"GALT112I-LF","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2b54741e388311a86c0c5910331119d8_014968d6-4589-4ae2-ac90-63acbc10966b.jpg?v=1785451760","url":"https:\/\/voomisupply.com\/products\/sigma-811030618-straight-pipe-tee-1-1-2-in-fnpt-150-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
