Your cart is empty. Compatible with APEC Essence and Ultimate reverse osmosis systems and also can be used on other 10" standard sized filter housings.
Made of high quality nitrile rubber that is flexible and resistant to abrasion and tearing.
Lightweight and super flexible construction allows o-rings to be easily installed and unloaded. Durable and not easy to break.
The dimensions of these o-rings are 3.5" OD..
We recommend replacing the o-ring every 1-2 years. We recommend using the product with a food grade lubricant for a better seal.

I had a leak and didn't know it for awhile. No real damage done but I did get water leak detectors. I have a video on you tube on bobeaseshop if you want to see how it all turned out.

The filter housing #1 of my APEC system (ROES-50 3.5" OD Reverse Osmosis Water Filter) was leaking so I decided to replace the O-rings. These rings should fit perfectly, but seemed to be just a bit big and it was impossible to end the leak. Finally, I bought a new filter housing, which came with a pre-installed O-ring, and that fixed the problem.
