One New Aftermarket Replacement Seal Buffer for Caterpillar (Cat) Large Excavators and Front Shovels
This aftermarket replacement seal buffer fits Caterpillar large excavators and front shovels, including the 365B, 365C, 385C, and 5090B series. The seal buffer is a hydraulic cylinder component positioned in front of the primary rod seal to absorb shock and reduce pressure spikes, protecting the primary seals from damage during demanding digging and lifting cycles. Replacing a worn or damaged seal buffer helps prevent hydraulic fluid leakage, extends cylinder service life, and maintains optimal hydraulic system performance.
