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.
