Specs At A Glance

Good To Know

Q: Should the O-ring be replaced every time the filter cover is removed? A: Yes, an old O-ring can harden or flatten and lose its seal once disturbed, so fitting a fresh one with each filter service is the safe practice.

Q: Does this O-ring need sealant to work? A: No, it is designed to seal on compression alone once the cover is torqued, so keep the groove clean and free of old material before installation.

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