Proper sealing helps maintain system pressure and supports smooth equipment operation.
Which Caterpillar equipment may use the 2K8257 or 2J3123 seal O-ring?
Compatibility of the 2K8257 can differ depending on the machine model and serial number. Verify fitment in your service manual before purchasing, or reach out to Propel Parts — our team can quickly confirm the right part for your equipment.
What are the signs that a Caterpillar seal O-ring needs replacement?
