Freudenberg-NOK Sealing Technologies says General Motors has selected its low load seal technology.

The equipment is a type of offset seal that can be installed and removed by hand, with Freudenberg maintaining it reduces installation force by more than 70%

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.

“The design allows for the use of dissimilar mated materials and reduces stress on components, which contributes to increased durability.”
