The o-rings under each Dzus quarter turn fastener head are vital components in the water resistant seal design. These o-rings are coated with Super Lube synthetic grease at installation to insure smooth fastener turning while at the same time resisting water penetration into the canister. After a few seasons you may want to remove the snap ring and clean the fasteners, o-rings and seats if you notice the torque has grown uncomfortable. "Re-greasing" of the o-ring seals must be done with Super Lube synthetic grease or equivalent.
