Designed for grooved-end pipe systems, this rigid coupling mechanically joins pipe segments while maintaining a fixed, rigid joint that prevents angular deflection. The ductile iron body provides high-strength performance in demanding mechanical and industrial piping applications. The CenterLok EPDM gasket seats securely within the housing to maintain a reliable seal. Licensed plumbers, pipefitters, and mechanical contractors are the primary installers of this type of coupling in commercial and industrial systems.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for 8-inch grooved-end pipe installations in commercial mechanical systems, industrial process piping, fire protection, HVAC hydronic distribution, and similar applications where a rigid joint is required. The painted finish provides basic corrosion resistance for typical interior service environments. It is intended for use wherever Gruvlok-style grooved mechanical couplings are specified and a rigid connection is required at the joint.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRigid coupling design prevents angular deflection at the joint for fixed-pipe configurations\u003c\/li\u003e\n  \u003cli\u003e74CL Sabertooth housing geometry provides positive pipe-end engagement on grooved pipe\u003c\/li\u003e\n  \u003cli\u003eCenterLok EPDM gasket self-centers within the coupling for consistent sealing\u003c\/li\u003e\n  \u003cli\u003eDuctile iron construction delivers high tensile strength and impact resistance\u003c\/li\u003e\n  \u003cli\u003ePainted exterior finish for corrosion protection in standard interior service conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style grooved mechanical coupling for 8-inch grooved-end pipe systems where rigid Gruvlok-style couplings are specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed pipefitters or plumbers in accordance with applicable mechanical codes. Depressurize and drain the piping system fully before removing or installing any grooved coupling. Inspect pipe ends to confirm proper groove dimensions and condition before assembly. Lubricate the EPDM gasket per standard grooved coupling practice and torque housing bolts evenly to seat the gasket uniformly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Material\u003c\/strong\u003e: Ductile Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGasket Material\u003c\/strong\u003e: EPDM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Style\u003c\/strong\u003e: Rigid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Painted\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: 390213218\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51234088943922,"sku":"0390213218","price":184.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307631257.webp?v=1780117324","url":"https:\/\/voomisupply.com\/products\/asc-390213218-gruvlok-8in-74cl-sabertooth-rigid-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
