Q: How often do I need to change my filter housing's o-ring?

Captain O-Ring's high quality replacement water filter housing o-rings are designed for reliable extended use. 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?

You can if you'd like to. Generally a brand new buna-n o-ring can be installed just with wetting it with water. However, these o-rings are compatible with all silicone and petroleum based lubricants, as well as natural oils like vegetable oil.

Q: What if I don't know what o-ring part number my filter housing needs?

Use our handy printable water filter housing o-ring size chart. Print out the chart and lay your old o-ring on the page to see which o-ring it matches with. You can find the size chart listed as "User Guide [PDF]" under "Product guides and documents"

Q: Are these o-rings safe for use in my drinking water?

Yes! These Captain O-Ring replacement o-rings are molded from NSF 61 certified buna-n rubber for safe and clean drinking water.

Q: Where is this o-ring kit assembled?

Proudly assembled in the USA! We hand assemble these kits in Gloucester City, New Jersey.
