Constructed from ductile iron and finished with a painted coating for corrosion resistance, this 1-1\/2 inch coupling is built for mechanical piping systems in commercial and industrial applications. It provides a fast, bolt-together connection without welding or threading, making it a practical choice for HVAC hydronic piping, fire protection, and industrial process piping. Licensed pipefitters and mechanical contractors are the primary installers of grooved couplings in these systems.\u003c\/p\u003e\n\u003cp\u003eThis coupling is sized for 1-1\/2 inch grooved pipe and is suited for use in hydronic heating and cooling systems, chilled water and condenser water piping, fire suppression systems, and general industrial fluid handling. The rigid design maintains pipe alignment and prevents angular deflection at the joint, which is important in systems with fixed routing and no need for expansion compensation. It is typically installed in pairs or as part of a larger grooved piping assembly using compatible Gruvlok fittings and gaskets.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRigid joint design maintains pipe alignment and eliminates angular deflection\u003c\/li\u003e\n  \u003cli\u003eDuctile iron construction provides high strength and impact resistance\u003c\/li\u003e\n  \u003cli\u003ePainted finish adds a layer of corrosion protection for the coupling housing\u003c\/li\u003e\n  \u003cli\u003eGrooved connection eliminates welding and threading for faster installation\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch pipe size fits standard grooved pipe ends per AWWA and ANSI groove specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-fit coupling for 1-1\/2 inch grooved piping systems using Gruvlok-compatible fittings, gaskets, and pipe ends.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed pipefitters or mechanical contractors. Depressurize and drain the affected piping section before disassembly or coupling installation. Lubricate the gasket per the manufacturer gasket lubricant recommendation before seating, and confirm the groove dimensions meet the required specification before torquing the coupling bolts evenly to achieve uniform gasket seating. Follow applicable mechanical codes including ASME B31.9 for building services piping where required.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1-1\/2 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\u003eItem Weight\u003c\/strong\u003e: 2.02 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: 390013506\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51233507017010,"sku":"0390013506","price":53.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307631150.jpg?v=1780101686","url":"https:\/\/voomisupply.com\/products\/asc-390013506-gruvlok-rigidlok-grooved-coupling-1-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
