GM has adopted the design for several engine applications including a spark plug tube, vacuum pump seal and two solenoid-to-cam cover seals.

“Offset seals control independent loading on mated components and can be easily assembled or removed, allowing options for serviceability,” said engineering manager, Freudenberg-NOK engineering manager, David Pehlman.
