One New Aftermarket Replacement Buffer Seal for Caterpillar (Cat) Equipment
This hydraulic buffer seal replaces Caterpillar (Cat) part number 170-9845 and is designed for use in lift and hoist cylinder applications. Buffer seals are installed in hydraulic cylinders to protect the primary rod seal from pressure spikes -- their channeled design allows normal fluid flow under standard operating conditions while restricting sudden pressure surges before they can reach and damage the main rod seal. Keeping this seal in good condition is essential for reliable hydraulic cylinder performance on Caterpillar construction equipment.
