Topseal™, an intelligent topographic sealing system developed by ElringKlinger, is used mainly in manual and automatic transmissions, rear-axle transmissions, steering gears, auxiliary units, pumps and oil pans.
Owing to the elastomer seal in combination with the topographical structure of the metal housing component, Topseal™ exerts homogeneous compression over the entire sealing surface. It replaces conventional multi-part sealing systems, as well as reducing the need for bolts and scaling down weight and the cost of assembly. A reliable and economical solution.
