Parker WEAR-Lok Seals


Parker’s new patent-pending WEAR-Lok Seal for dovetail and undercut grooves offers significant advantages over traditional seal shapes where improved retention is needed. The WEAR-Lok Seal features intermittent “lobes” protruding from the sides of the seal which extend below the undercut feature retaining the seal in the groove but not affecting proper seal orientation.

The “lobe” features are designed to aggressively contact the groove walls providing reliable retention. The Parker WEAR-Lok Seal will remain deeply seated in a groove which has eroded beyond service limits when compared to a traditional seal shape.
