Built from ductile iron with a painted exterior finish, this coupling clamps onto grooved pipe ends to create a secure, zero-flex joint. At 8.05 pounds, it is sized for heavier-duty applications where pipe movement must be fully restrained. Licensed mechanical contractors and pipefitters install this type of coupling in commercial and industrial settings where grooved piping systems are specified over threaded or flanged alternatives.\u003c\/p\u003e\n\u003cp\u003eThe 390013563 rigid grooved coupling is used in commercial HVAC hydronic systems, fire protection piping, industrial process lines, and mechanical rooms where rigid joint performance is required. The grooved end connection method speeds up installation compared to welded or flanged joints, making it a common choice on new construction and retrofit projects. This coupling fits 6-inch grooved pipe prepared to standard groove specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRigid coupling design restrains angular and linear pipe movement at the joint\u003c\/li\u003e\n  \u003cli\u003eDuctile iron construction for strength and durability in pressurized piping\u003c\/li\u003e\n  \u003cli\u003ePainted exterior finish provides basic corrosion protection during installation and service\u003c\/li\u003e\n  \u003cli\u003e6-inch nominal pipe size fits standard grooved pipe ends\u003c\/li\u003e\n  \u003cli\u003eGrooved connection method reduces installation time versus flanged or welded joints\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style rigid grooved coupling for 6-inch grooved pipe systems in commercial HVAC, fire protection, 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 mechanical contractor familiar with grooved piping systems. Shut down and depressurize the piping system completely before removing or installing any coupling. Verify that pipe ends are cut and grooved to the correct dimensions for the 6-inch coupling before assembly. Follow the manufacturer torque specifications on the housing bolts and inspect the gasket seating before returning the system to service.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\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: 8.05 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: 390013563\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51233748091186,"sku":"0390013563","price":145.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307631152.jpg?v=1780108237","url":"https:\/\/voomisupply.com\/products\/asc-390013563-gruvlok-7401-e-rigidlok-grooved-coupling-6-in","provider":"Voomi Supply","version":"1.0","type":"link"}
