Manufactured from malleable iron with a galvanized finish, this fitting provides a branch outlet at a reduced diameter while maintaining flow continuity in the run. It carries a 150 lb pressure rating and uses female national pipe taper (FNPT) threads on all three ports. The galvanized coating resists corrosion in wet or exposed environments. Licensed plumbers and pipefitters install this fitting as part of new construction or retrofit piping systems requiring a directional branch with a size reduction at the branch or run outlet.\u003c\/p\u003e\u003cp\u003eThis reducing tee is suited for residential and commercial piping applications where a 3\/4 inch run connects to a 1\/2 inch branch. Common use cases include domestic water distribution, gas piping within code-permitted configurations, compressed air lines, and hydronic heating systems. The FNPT thread pattern conforms to standard pipe thread specifications, making it compatible with standard threaded pipe and fittings of the same nominal size and thread form.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eReducing tee configuration: 3\/4 x 1\/2 x 3\/4 inches nominal for in-line branch reduction\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 installations\u003c\/li\u003e\n\u003cli\u003eFNPT threads on all three ports for standard threaded pipe connections\u003c\/li\u003e\n\u003cli\u003eFIG 3105R pattern — a widely recognized reducing tee configuration in trade piping work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style threaded fitting replacement or new-installation component for 3\/4 x 1\/2 x 3\/4 inch nominal FNPT threaded pipe systems rated to 150 lb service class.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing or mechanical codes, including IPC and IFGC where relevant. Shut off and depressurize the pipe system completely before cutting in or replacing any threaded fitting. Apply appropriate thread sealant or PTFE tape to male threads before assembly, and tighten to proper engagement without over-torquing malleable iron threads. Inspect the galvanized coating for damage after installation if the fitting will be exposed to standing water or buried conditions.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 3\/4 x 1\/2 x 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: FNPT (Female National Pipe Taper) all 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\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: 811038710\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51525508104498,"sku":"GALTRED341234I-LF","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/76dfead0281cef7a6c3ed6387e524d84_a36f2618-9ac3-4e65-ad1e-72b4ce33907f.jpg?v=1785475946","url":"https:\/\/voomisupply.com\/products\/sigma-811038710-malleable-iron-reducing-tee-3-4x1-2x3-4-150lb","provider":"Voomi Supply","version":"1.0","type":"link"}
