Description
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.
