## Questions & Answers

**Q: How often do I need to change my filter housing's o-ring?**
A: 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?**
A: 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?**
A: 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?**
A: 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?**
A: Proudly assembled in the USA! We hand assemble these kits in Gloucester City, New Jersey.
