Profile BA PARK-O-PAK® is the consequence of a further development of the lipseal. It combines the advantages of a highly elastic O-ring and the abrasion resistance of a lipseal compound.

This special seal is mainly used in the mobile hydraulic industry because of its special feature – the fitted O-ring.

The O-ring guarantees the preloading of the seal lips under low pressure or vacuum; this is necessary for the sealing function.

The sealing force is largely independent of temperature variations, and it ensures the necessary preloading even if a certain amount of abrasion takes place. The lip is loaded according to increasing system pressure, transmitted through the pressure-dependent deformation of the O-ring.
