The gasket forms the pressure-retaining seal inside the coupling housing, gripping the grooved pipe ends to maintain a leak-free joint across a range of piping system pressures and temperatures. At 0.10 pounds, it is a lightweight but critical component in grooved mechanical piping systems. Licensed pipefitters, plumbers, and mechanical contractors install this gasket during new construction and retrofit work on grooved-end piping assemblies in commercial and industrial applications.\u003c\/p\u003e\n\u003cp\u003eThis gasket is sized for 4-inch pipe and is compatible with Gruvlok 7000 and 7001 grooved couplings. Grooved piping systems are common in commercial HVAC hydronic loops, fire protection systems, and industrial process piping where fast, re-enterable mechanical joints are preferred over welded or threaded connections. Buna-Nitrile (NBR) elastomer is a standard gasket material suited for water, air, and a broad range of petroleum-based fluids.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-Nitrile (NBR) elastomer construction for compatibility with water, air, and petroleum-based media\u003c\/li\u003e\n  \u003cli\u003eSized for 4-inch grooved pipe couplings\u003c\/li\u003e\n  \u003cli\u003eDesigned to fit Gruvlok 7000 and 7001 coupling housings\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.10 pounds for easy handling during installation\u003c\/li\u003e\n  \u003cli\u003eProvides the primary pressure seal in the grooved coupling assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Gruvlok 7000 and 7001 grooved pipe couplings in 4-inch pipe size configurations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis gasket is installed by licensed pipefitters or plumbers as part of a grooved mechanical coupling assembly. De-pressurize and drain the piping system before disassembling any grooved coupling for gasket replacement. Inspect the pipe groove and coupling housing for damage or debris before seating the new gasket. Follow the coupling manufacturer torque specifications for the housing bolts and lubricate the gasket per the coupling manufacturer guidance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGasket Material\u003c\/strong\u003e: Buna-Nitrile (NBR)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Material\u003c\/strong\u003e: Ductile Iron (coupling housing reference)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eItem Weight\u003c\/strong\u003e: 0.10 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: 390079200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51233399472434,"sku":"0390079200","price":54.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307627641.jpg?v=1780099051","url":"https:\/\/voomisupply.com\/products\/asc-engineered-solutions-390079200-buna-nitrile-gasket-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
