We recommend consumers keep a spare o-ring on hand to avoid urgent situations. An o-ring facilitates a water tight seal between the water filter sump and the water filter head. The most common o-rings used in water filtration are made from Buna N material. Buna N is also commonly referred to as nitrile. This is the ideal choice for cold water filtration because they are inexpensive and have superior performance characteristics. KleenWater is a trademark of Pavel Water Filtration. Enter KW217-RG217 in the Amazon Search Bar to purchase a cartridge with o-ring kit.

I installed by original system 25 years ago. I am glad the cartridges are still available. This is a very economical way to filter water at the tap for drinking. Rapid flow is better than the pitchers filters. Forget those plastic water bottles.

I have replaced my AP200 filters before, and have tried to re-use the stock O-rings. Forget about doing that! I had too many times of replacing the filters and having to deal with leaks. These O-rings are a good value, and I haven’t had to deal with a leak from the unit since I started using them. I no longer re-use my O-rings.

I like the product.What I don't like is that I just checked my bank statements and noticed Amazon took $99. Out of my account without my permission for amazon prime or something. I will be calling.
