This concentric reducer transitions from a 4-inch nominal inlet to a 2-inch nominal outlet, making it a standard component in water supply, fire protection, and general industrial piping installations. The galvanized finish provides corrosion resistance for both wet and dry service environments. Licensed plumbers and pipefitters typically source this fitting for commercial and light industrial applications where a durable, code-compliant threaded connection is required.\u003c\/p\u003e\u003cp\u003eThis reducer is suited for use in residential and commercial piping systems where a reduction from 4-inch to 2-inch nominal pipe size is needed. Typical applications include water distribution mains, branch line connections, and mechanical room piping assemblies. The malleable iron construction handles the mechanical stress of threaded assembly and the pressure demands of standard plumbing and fire protection systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-inch to 2-inch nominal pipe size reduction in a single threaded fitting\u003c\/li\u003e\n\u003cli\u003eMalleable iron construction for strength and resistance to cracking under stress\u003c\/li\u003e\n\u003cli\u003eGalvanized finish for corrosion protection in wet service environments\u003c\/li\u003e\n\u003cli\u003eThreaded connection compatible with standard NPT pipe threads\u003c\/li\u003e\n\u003cli\u003eSuitable for water supply, fire protection, and general industrial piping\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard-supply fitting for threaded malleable iron piping systems using 4-inch to 2-inch nominal pipe sizes.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or local plumbing code requirements. Shut off and depressurize the piping system fully before removing or installing any threaded fittings. Apply an approved thread sealant or PTFE tape to male threads before assembly, and tighten to a snug, leak-free connection using a pipe wrench — do not overtighten malleable iron fittings, as the material can crack under excessive torque. Inspect the joint for leaks after system pressure is restored.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 4 inches nominal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 2 inches nominal\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\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: 811093012\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51523524788530,"sku":"GALRED42I-LF","price":64.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f0eabc50583c61a419da8ef4f53862fd_e8eed0ea-023d-4f95-8110-e0fd80c27b6d.jpg?v=1785442594","url":"https:\/\/voomisupply.com\/products\/sigma-811093012-galvanized-malleable-iron-reducer-4x2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
