Built to FIG 3105R dimensions, this tee connects a 1-inch run on both the inlet and outlet with a 3\/4-inch branch outlet, all in female NPT (FNPT) thread configuration. The galvanized finish provides corrosion resistance suited for water supply, compressed air, and low-pressure steam applications. Licensed plumbers, pipefitters, and HVAC technicians rely on this fitting for reliable, leak-free reductions within threaded iron pipe systems.\u003c\/p\u003e\n\u003cp\u003eThis reducing tee is used in residential and light commercial piping installations where a branch line steps down from a 1-inch main to a 3\/4-inch takeoff. Typical applications include water distribution headers, gas supply manifolds, compressed air lines, and HVAC hydronic systems. The FNPT end style accepts standard NPT male-threaded pipe or nipples on all three ports, making assembly straightforward with conventional pipe wrenches and thread sealant.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFIG 3105R reducing tee with 1 x 1 x 3\/4 inch nominal sizing for inline branch reduction\u003c\/li\u003e\n  \u003cli\u003e150 lb pressure rating suitable for water, air, and low-pressure steam service\u003c\/li\u003e\n  \u003cli\u003eFemale NPT threads on all three ports for standard threaded pipe assembly\u003c\/li\u003e\n  \u003cli\u003eMalleable iron construction provides strength and impact resistance over cast iron\u003c\/li\u003e\n  \u003cli\u003eHot-dip galvanized finish resists corrosion in wet and humid environments\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 threaded malleable iron pipe systems using 1-inch and 3\/4-inch NPT-threaded pipe or nipples 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 local plumbing codes and IFGC requirements where gas service is involved. Shut off and depressurize the line completely before disassembling existing fittings or threading new connections. Apply an appropriate thread sealant or PTFE tape to all male NPT threads before assembly, and tighten with a pipe wrench to achieve a leak-free joint. Do not overtighten, as malleable iron threads can be damaged by excessive torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFigure Number\u003c\/strong\u003e: FIG 3105R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1 x 1 x 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: FNPT (Female NPT) 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: Galvanized\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: 811039809\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51524528767282,"sku":"GALTRED1134I-LF","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/76dfead0281cef7a6c3ed6387e524d84_f0f9166b-5b77-4d85-8770-0a0884f93063.jpg?v=1785450943","url":"https:\/\/voomisupply.com\/products\/sigma-811039809-galvanized-reducing-tee-1x1x3-4-in-fnpt-150-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
