Constructed from ductile iron with a painted finish, this fitting delivers the mechanical strength and corrosion resistance required in demanding piping installations. The concentric design keeps the pipe centerline aligned, which is critical in horizontal runs where consistent flow path alignment matters. Licensed pipefitters and mechanical contractors install this fitting as part of grooved mechanical joining systems in commercial and industrial applications.\u003c\/p\u003e\n\u003cp\u003eThis reducer is suited for commercial and industrial piping systems where grooved-end mechanical couplings are the joining method of choice. Typical installations include HVAC hydronic systems, fire protection piping, and process piping where a 6-inch-to-4-inch diameter reduction is required. The grooved ends mate directly with standard grooved couplings, eliminating the need for welding or flanging at the transition point.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eConcentric reducer design maintains centerline alignment in horizontal and vertical piping runs\u003c\/li\u003e\n  \u003cli\u003eDuctile iron construction provides high tensile strength and impact resistance\u003c\/li\u003e\n  \u003cli\u003ePainted exterior finish offers baseline corrosion protection for above-ground installations\u003c\/li\u003e\n  \u003cli\u003eGrooved ends are compatible with standard grooved mechanical coupling systems\u003c\/li\u003e\n  \u003cli\u003e6-inch x 4-inch size handles common large-to-mid-range pipe diameter transitions\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 mechanical coupling systems on 6-inch and 4-inch schedule pipe in commercial and industrial piping applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed pipefitter or qualified mechanical contractor familiar with grooved piping systems. Depressurize and drain the piping system fully before removing or installing any grooved fitting. Verify that pipe ends are properly rolled or cut-grooved to the correct groove specification before seating the coupling. Follow applicable mechanical codes including ASME and local authority having jurisdiction requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 6 inches x 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Material\u003c\/strong\u003e: Ductile Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Painted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\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\u003eItem Weight\u003c\/strong\u003e: 5.66 pounds\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: ASC Engineered Solutions\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 390028967\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51233738391858,"sku":"0390028967","price":152.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307631126.jpg?v=1780107922","url":"https:\/\/voomisupply.com\/products\/asc-390028967-gruvlok-7072-6x4-grooved-concentric-reducer","provider":"Voomi Supply","version":"1.0","type":"link"}
