Recommend replacing o rings every time you replace your filters. Great value

I can’t imagine buying an important part like the O ring seals from anyone but the manufacturer, APEC O rings are a perfect fit, high quality material. I typically replace them along with the filter cartridges each year just for piece of mind. Our RO-45 system has had zero failures with ten hard years of use.

I had another T.R.O. system from a company in Canada and always had problems. I finally gave up on them and with trepidation tried another company; this one. APEC Water Systems Triple Reverse Osmosis system works great and after a year I have had no problems. This was my first filter change out with this brand and I couldn’t be happier. You will not have any leaks if you follow the recommendation of purchasing not only new Orings, but the food grade lubricant that goes with it. Thanks Apec for a great product!!

I bought the o-rings for peace of mindsince it was time to replace the 3 filters. 1 of the 3 rings was too large, so I had toreuse an old one. Fortunately it did not leak after installing the new filters.

Changed the “O” rings last time (1 yr ago) – didn’t need to replace this time, would hate to think about the water damage if they were needed and not on hand

I replace the o-rings for my filters often, I’ve never had a leak but I never expect any leaks because of the new rings.

Had not replaced the O-rings during the last three filter changes. Last time I replaced I had leaks and had to over tighten in order to get it to stop. Purchased these as it was way over-due. Old rings were flattened and less pliable than the new ones. Also bought the O-ring lubricant to go with it and this made a huge difference during installation and with preventing leaks as well. Highly recommended.

Just ok, they used the minimum amount of rubber compared to the original
