One New Aftermarket Replacement Kit-Rear Seal for Caterpillar (Cat) Equipment
This aftermarket replacement rear seal kit is designed to restore sealing integrity within Caterpillar (Cat) hydraulic and mechanical assemblies. Rear seal kits are used to prevent fluid leaks at the rear of a pump, motor, or drive assembly, protecting internal components from contamination and maintaining system pressure. Replacing worn or damaged seals with a complete kit ensures all sealing elements are refreshed at once, reducing the risk of repeat failures and unplanned downtime.
