Still, it is typically recommended to replace your o-ring on every third filter change to ensure it is in top shape to prevent leaks. **Q: Can I use grease or lubricant on these o-rings?** A: You can if you'd like to.

Print out the chart and lay your old o-ring on the page to see which o-ring it matches with.
