One New Aftermarket Replacement Buffer Seal for Caterpillar (Cat) Construction Equipment
This aftermarket replacement Buffer Seal (Seal-Buffer) replaces Caterpillar (Cat) OEM part number 170-9844. Buffer seals are hydraulic cylinder components that absorb pressure spikes and shock loads, protecting the primary rod seal from premature wear and extending the overall service life of the hydraulic cylinder sealing system. This seal is sold individually.
Part Function
Installed in the hydraulic cylinder rod gland ahead of the primary U-cup or rod seal, the buffer seal reduces stress on the main sealing elements by dampening dynamic pressure surges. Proper buffer seal maintenance helps prevent hydraulic fluid leaks and keeps cylinders operating reliably under demanding load cycles typical of Cat construction and earthmoving equipment.
