SELF-CONTAINED LOW LOAD NARROW GROOVE SEAL

Abstract:

A friction fit seal provides enhanced stability and installation as compared to conventional configurations. The seal includes a seal body having a longitudinal axis; a retention rib that extends from the seal body in a lateral direction perpendicular to the longitudinal axis; and at least one stabilizer rib that extends from the seal body in the lateral direction and is spaced apart from the retention rib along the longitudinal axis. A lateral width of the stabilizer rib in the lateral direction is smaller than a lateral width of the retention rib. The seal may be a keyhole seal in which the seal body includes an inner surface and an outer surface, and the inner surface defines a hollow center that may be keyhole shaped. The seal may include a solid central main body, and the stabilizer ribs and the retention rib are configured as lobes that extend in the lateral direction from the solid central main body.
