One New Aftermarket Replacement Ring-Seal for Caterpillar (Cat) Construction Equipment
This aftermarket replacement ring-seal (cushion seal) is used in Caterpillar hydraulic cylinders found on construction equipment. Cushion seals are typically made from nylon or phenolic material and limit fluid flow through the port at the end of the cylinder stroke, cushioning the movement of the cylinder rod and protecting the cylinder from impact damage. Replacing a worn or damaged ring-seal restores proper hydraulic cylinder function and helps prevent fluid leaks.
