The Curve Gasket elastomeric static seal from Freudenberg-NOK Sealing Technologies supports the powertrain design trend for lightweight components. With greater stability, lower reaction forces, and wider compression ranges, the Curve Gasket reduces the amount of structural plastic required in engine covers. A combination of constant and undulated cross-sections reduce loading, with the undulated sections applying the same design principle as the corrugated waves used to stabilize metal sheeting. The design improves stability in smaller grooves, including the thermoplastic covers on new engine designs. The Curve Gasket is fine-tuned to optimize performance based on the sealing application. The design allows a shift of compression range to a higher level while reducing reaction forces and prevents the gasket from exceeding the void volume limit at elevated temperatures.
