Good To Know

Q: Is this an original Sea-Doo part? A: No, this is an aftermarket replacement O-ring that cross-references OEM part number 420850500. It is designed to fit the same location as the original seal.

Q: How often should the O-ring be replaced? A: The O-ring should be inspected and typically replaced whenever the oil filter cover is removed for service. A hardened or flattened seal can lead to oil leaks over time.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
