This heavy-duty ductile iron coupling connects plain-end pipe sections without requiring grooved pipe ends, making it suitable for industrial and commercial piping applications where standard grooved couplings are not an option. Weighing 23.75 pounds and sized for 5-inch pipe, it is built for demanding service environments. Plumbers, pipefitters, and mechanical contractors are the typical trade professionals who install and service this type of fitting.\u003c\/p\u003e\n\u003cp\u003eThis coupling is intended for use in commercial and industrial piping installations where plain end connections are required. It is commonly found in fire protection, HVAC hydronic systems, and general mechanical piping where the Gruvlok product platform is specified. The 5-inch size suits larger-diameter piping runs typical of main distribution headers and primary mechanical room piping. Installation is performed by licensed pipefitters or journeyman plumbers following applicable mechanical and fire codes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePlain end design eliminates the need for grooved or threaded pipe preparation\u003c\/li\u003e\n  \u003cli\u003eDuctile iron construction provides high strength and impact resistance\u003c\/li\u003e\n  \u003cli\u003e5-inch pipe size suits large-diameter commercial and industrial runs\u003c\/li\u003e\n  \u003cli\u003ePart of the Gruvlok Roughneck product line for heavy-duty mechanical service\u003c\/li\u003e\n  \u003cli\u003eSubstantial 23.75-pound unit weight reflects robust material cross-sections\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style plain end coupling for use in Gruvlok-compatible grooved piping systems on 5-inch pipe.

Depressurize and isolate the piping system completely before removing any existing fittings or installing this coupling. Inspect pipe ends for burrs, ovality, or damage prior to assembly, as plain end couplings depend on clean, round pipe ends for proper sealing. Follow the manufacturer torque sequence and fastener specifications provided with the coupling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Material\u003c\/strong\u003e: Ductile Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eItem Weight\u003c\/strong\u003e: 23.75 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: 390007425\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51233434960178,"sku":"0390007425","price":377.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307631130.jpg?v=1780099924","url":"https:\/\/voomisupply.com\/products\/asc-390007425-gruvlok-roughneck-plain-end-coupling-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
