Replacement O-Ring for ROES-50, 3.5" OD, 3 Count, Black

This was a perfect fit for my water system. Just make sure to carefully look at the photo description as this company makes two sizes! it's very easy to accidentally choose the wrong one if you are not paying attention. All you have to do is match the filter housing to the photo and you will know if it will fit or not. I applied some food-grade silicone to the O-ring to give it a better seal. You can also put some of that silicone on the rubber gaskets on both sides of the carbon filters (stages 2-3). This helps it seal much better. I noticed that if I did not apply the silicone to the carbon filters there is usually a buildup of gunk (??) on the top seal which tells me the seal may not have been performing as it should. I love the APEC Roes-50 water system! It has made a huge difference in our water quality (and we sure don't miss having to carry all of those heavy 5-gallon water bottles from the store)!

This worked out fabulous! My son replaced the filters. He was glad I ordered the APEC O Rings for the filters. I went to Home Depot and Lowe's who both told me they had Apec Filters and O Rings. After driving 30 minutes to pick them up they tried selling me a GE set. I refused to get those and came home and was glad Amazon had them.This worked out fabulous! My son replaced the filters.

It's hard to sit the ring in the socket - this is obviously larger than the original ones. But once installed it fixed the leak.

Must have if your going. To replace those filters. Cheap

Figured I would change the o-rings with the filters to lessen the chance of any leaks. These o-rings are the APEC brand and not aftermarket. I put a little bit of plumbers silicone grease on them prior to installing. O-rings were a little bit oversized which I thought was odd. I installed them best as possible and no leaks. Due to size versus what was in there from new I gave 4 stars instead of 5. So far so good, no leaks. I have the ROES-50 system on my kitchen sink, great low cost system that removes all weird taste from my municipal supplied water. Glad I have this system. Update: 12/2/20 - product page has changed and now there is a set B available. Per the ordering instructions my filter canister housings matched their callout for set B. Upon installation the B O-Rings were undersized and not laying flat in the housing channels. I reinstalled the set A from the last service, thankfully no leaks. Not sure what the problem is with getting O-Rings that seat correctly. Amazon made right as usual and refunded the purchase price. I made notes and will order set A next go around and see what happens.

I tried the APEC Water Systems SET 3 Pcs 3.5" O.D. Replacement O-Ring, and it's a lifesaver. The three-piece set ensures a snug fit for reverse osmosis water filter housings. The black O-rings are durable and efficient, sealing tight to prevent leaks. If you're maintaining a water filtration system, this replacement set is a reliable choice.

Used in conjunction with point of use water filtering kits. Helps prevent leaking filter housings. Fits apec reverse osmosis pre filter housings.

Mine seemed too big for my filter housing but after tightening the cap it seemed they may have seated properly since I had no leaks.

المنتج صينى و الوصف اونطه مش امريكى و كاليفورنيا بس شغال لولا انى محتاجه كنت رجعته علشان يتعلم التاجر الصدق فى الوصف و طبعا السعر غالى بما انه صينى مش امريكى و محطوط فى كيس غريب

Original replacement parts.

One of our RO tubes was leaking and we had to replace the o rings. It took a while to find the right size but when we did it worked perfectly. No more leaking.

بس في أفضل من كدة

A little larger than the original, it’s ok for installation and no leak
