Frequently Asked Water Filter O-Ring Questions 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 desertcart page layout. Important Note #1: Does your filter housing use a square/flat gasket rather than a round o-ring? Some of the older 3M AP801 models use a flat (squared-off) gasket rather than the round o-ring. These housings use the 68898-31 gasket rather than the newer 68898-32 o-ring. If you need the flat 68898-31 gasket, you can find it below. Important Note #2: Do you have one of the newer 3M AP801B, AP801T, AP802B, AP802T housings? The newer 3M Aqua Pure AP801B/T and AP802B/T housings use the newer 3M #70-0203-5277-2 o-ring. It is slightly smaller in diameter than the older 3M 68898-32 o-ring. You can find it below if you have one of the newer 3M AP801B, AP801T, AP802B, or AP802T filter housings.
