Freudenberg-NOK Sealing Technologies offers a new elastomeric static seal as part of a global effort from its gaskets division. According to the company, the patent-pending curve gasket supports the trend of new powertrain modules with a focus on lightweight design. With greater stability, lower reaction forces, and wider compression ranges, the curve gasket helps minimize the amount of structural plastic required in engine covers. To achieve the dimensional stability and lower reaction forces essential for sealing lightweight thermoplastic covers, the curve gasket uses a combination of constant and undulated cross-sections that reduce loading. The undulated sections of the gasket use the same design principle as the corrugated waves used to stabilize metal sheeting. Fine-tuned to optimize its performance based on the sealing application, the curve gasket’s design allows a shift of compression range to a higher level while reducing reaction forces.
