Frequently Asked Questions:

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

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?

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.

I tried O-rings from the local hardware store, the local plumbing supply, and then these for my W–10 PR. These work. Don’t bother with the others.

Fits my whole house water filter housing perfectly. Good price so should replace the seal each time you replace the filter. Be sure to use the proper silicone lube on it when installing the seal.
