Impresa O-Rings Water Filter Replacement Gaskets - 6 Pack - Tight Seal and Stops Leaks - Quick and Easy to Install - Compatible with Whole Home Water Filtration System (2.5 in)

Worked really well Harbor freight did not have it thanks a lot Amazon

I had a problem with one because it was small but I put some heat on it until it fit.

I got these the next day with Amazon Prime. These fit perfectly in my GE GX1S01R, replacing the old o-ring, which was damaged by time. Now I have enough for the next 5 water filter replacements. Good deal.

Perfect

Great! Be sure to stretch them slightly before you install them or they won't work. Not the products problem, the installers.

This is one of those items that one simply must have in good working order, when changing a cartridge filter on a whole house water filter. I saw that the O-ring on my GXWH20F, which I had been using for years without issue was beginning to stretch and would likely fail on the next cartridge change.I ordered one of these Impressa Water Filter Replacement Gasket 6-Packs. When it came time to replace the cartridge, there was no way any of these would fit in and stay in the filter housing groove. They are a couple of mm too small in circumference and though they can be stretched, the O-ring would not stay in the groove of my filter unit. Using the silicone grease just made it worse to slip out of its groove. I tried one anyway and had a gusher at the seal.And yes, the original O-ring on my GXWH20F did indeed fail, when I tried to reuse it during this cartridge change.These things never happen in prime time, as was the case here. It was after 4PM on a Sunday afternoon, and on a holiday weekend to boot. A round of the local stores was looking pretty grim, until I found a replacement (orange big box store) specific to my filter.An Impressa O-ring such as in this pack might work on a brand new GXWH20F, where the cartridge housing has not been in use for some time and the inside edge of the groove is not worn at all. A stretched ring might stay in this case. Maybe. Maybe not. I cannot say.Yet as I wrote in the beginning, when one is faced with this sort of problem in this type of unit, one needs to have the right part instantly at hand. I fault Impressa for making the misleading claim that their product would fit my specific model GXWH20F. I specifically ordered a replacement a full month ahead based on their claim of compatibility ahead of time just to not have this situation. They wasted my money and my time and caused a great deal of inconvenience on a busy afternoon.

Thank you all!

I have had a ge filter for 20 years. When I changed the filter cartridge the o ring disappeared so I needed a replacement. My filter is working once again.
