Slimline sealing washers for electric vehicle HVAC hose connections and EV battery and electronic unit cooling systems that combine the function of a rubber seal with that of a metallic washer in one composite seal Composite sealing washers combine the function of a rubber seal such as an O-ring with that of a metallic washer in one bonded washer component. Their use aids in removing operational inefficiencies associated with component assembly and installation, and lessening warranty and rework costs associated with quality mistakes where visual inspection cannot assure the seal has been installed. Composite bonded sealing washers for electric vehicle hose connection and battery cooling systems provide advantages over molded elastomer shape seals which include: Elimination of machining costs. Use of composite sealing technology producing the combination seal ring and the metallic washer eliminates the need for an additional seal groove and reduces costs associated with machining tight tolerance sealing grooves. Mistake-proof installation. Damage to the seal due to incorrect installation or insufficient assembly forces is excluded due to the shape of the sealing ring and the defined torque levels of the screws. Lessen failures from quality inspection mistakes. With composite bonded sealing washers, the externally visible metal ring enables positive visual inspection and ensures the seal has been installed. Whereas using a separate molded elastomer seal, visual inspection cannot assure the seal has been installed.
