Frequently Asked Questions:

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

Can I use grease or lubricant on these o-rings?

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

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.

Can I use grease or lubricant on these o-rings?

Since Captain O-Ring supplies high quality o-rings without surface imperfections or tacky/sticky surface texture, lubrication is typically not needed if the filter housing sealing surfaces are clean and free of debris. Simply wet the o-rings with water before installing. However, if lubrication is preferred, these Buna Nitrile rubber o-rings are compatible with silicone based and petroleum based lubricants, as well as natural lubricants like vegetable oil.

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

Not sure which o-ring part number you need for your filter housing? Use our handy printable water filter housing o-ring size chart. Simply 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 the "Product guides and documents" section or the "downloads" section on this page, depending on your Amazon page layout.

I couldn't tell you what brand my filter cannister is. The O-ring had gotten stretched, and it was difficult to reinstall the new 4.5 x 10 filter. This was the correct one, and fit perfectly. Now I have 2 more spares.
