Abstract
Hydraulic cylinder rods on machines can be protected by applying a thin coating of protectant to the surface of the rod. The present invention provides a flexible, impervious sleeve having first and second ends and first and second edges connecting the ends. One end of the sleeve has a wiper portion which is secured around the cylinder rod while the other end of the sleeve is secured relative to the hydraulic cylinder. The edges of the sleeve wrap around the rod and a reserve of protectant and, when fastened together, form a closed member. Upon extension of the rod, the protectant is forced into the wiper portion and spread onto the rod.
