This fitting reduces pipe diameter from 4 inches to 2.5 inches and is finished with a protective painted coating to resist corrosion in typical mechanical system environments. It is installed by pipefitters and mechanical contractors working on fire protection, HVAC, and industrial piping systems where grooved-end connections are specified. The concentric design keeps the pipe centerline aligned through the transition, which simplifies layout and hanger placement in overhead and inline runs.\u003c\/p\u003e\n\u003cp\u003eThis reducer is suited for grooved mechanical piping installations in commercial and industrial applications. It is commonly used in wet-pipe and dry-pipe fire sprinkler systems, chilled water and condenser water loops, and process piping where a grooved-end fitting is required at a diameter transition. The painted finish makes it appropriate for exposed interior mechanical rooms and utility spaces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eConcentric reducer geometry maintains centerline alignment through the pipe size transition\u003c\/li\u003e\n  \u003cli\u003eGrooved ends on both sides are compatible with standard grooved mechanical couplings and housings\u003c\/li\u003e\n  \u003cli\u003ePainted exterior coating provides baseline corrosion protection for interior mechanical environments\u003c\/li\u003e\n  \u003cli\u003eReduces from 4-inch to 2.5-inch pipe for common diameter transitions in commercial piping systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style grooved fitting for use with standard grooved coupling systems in 4-inch to 2.5-inch pipe diameter transitions.

Depressurize and drain the piping system fully before removing any existing fittings or couplings. Inspect groove dimensions on both pipe ends to confirm they meet the required groove standard before seating the coupling housing. Follow the coupling manufacturer's bolt torque sequence to ensure proper gasket seating and a leak-free joint.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection Type\u003c\/strong\u003e: Grooved\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReducer Style\u003c\/strong\u003e: Concentric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Painted\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: ANVIL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 390028645\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ANVIL","offers":[{"title":"Default Title","offer_id":51150238253362,"sku":"0390028645","price":81.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305986845.jpg?v=1778608325","url":"https:\/\/voomisupply.com\/products\/anvil-390028645-grooved-concentric-reducer-4x2-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
