It reduces from a 4-inch nominal pipe down to a 2.5-inch nominal pipe, allowing for diameter transitions without additional fittings. The galvanized finish provides corrosion resistance suitable for water and general-purpose piping applications. This fitting is installed by licensed plumbers and pipefitters working on commercial or industrial piping systems where threaded malleable iron fittings are specified.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is used in threaded pipe assemblies where a reduction from 4-inch to 2.5-inch nominal pipe is required. Typical applications include water distribution, fire protection, and general-purpose industrial piping. The 150 lb pressure rating makes it appropriate for standard-service, non-shock, moderate-pressure piping systems in both new construction and retrofit work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces from 4-inch to 2.5-inch nominal pipe in a single threaded fitting\u003c\/li\u003e\n  \u003cli\u003e150 lb pressure rating for standard-service piping applications\u003c\/li\u003e\n  \u003cli\u003eMalleable iron construction provides strength and impact resistance\u003c\/li\u003e\n  \u003cli\u003eGalvanized finish resists corrosion in wet or humid environments\u003c\/li\u003e\n  \u003cli\u003eThreaded ends conform to standard NPT pipe thread dimensions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 150 lb class threaded malleable iron piping systems with a 4-inch by 2.5-inch nominal pipe reduction requirement.\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 plumbing codes such as the IPC. Shut off and depressurize the piping system fully before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not over-torque threaded connections, as this can crack malleable iron fittings.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 4 x 2.5 inches\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\u003eConnection Type\u003c\/strong\u003e: Threaded (NPT)\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: 811092808\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51523737878834,"sku":"GALRED4212I-LF","price":64.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f0eabc50583c61a419da8ef4f53862fd_43625e7d-c270-4a2e-87c1-85b91bdb2479.jpg?v=1785443707","url":"https:\/\/voomisupply.com\/products\/sigma-811092808-pipe-reducing-coupling-4x2-5-in-150lb-galvanized","provider":"Voomi Supply","version":"1.0","type":"link"}
