These are the perfect O-rings for the 4 ½ big blue filter bodies. I use a little Moly 111 O-ring lube every time I open a system.Great product. Great value.

I had gotten some other generic rings for my Big Blue 20" and while the diameter was correct and they fit into the groove, the actual thickness of the ring was not enough and I had leaks. Not so with this one, the ring appears to be a direct OEM replacement and worked perfected on my BB 20" system right away. Well priced for a pack of 4.

This is a good quality set of O rings that fit our large diameter approx 6 inch - 20 inch Big Blue water filter.They seal well with no leaks. I change the inside filters every 6-12 months depending on use and will replace the O ring if it gets dry or cracked. i always keep extra O rings as spares. I also use a silicone lubricant spray on the O rings when I change them. It seems to help prevent any leaks and keeps them from drying out. Overall, these are good O rings that fit the Big Blue water Filters.Thank you.

These O-rings are a perfect fit for my 20-inch long Big Blue water filters. They seal well with no leaks. I have 3 of the 20 inch long filters, 2 contain 5 micron sediment filters and one has a carbon filter. I change the filters every 5 months.The only time I have had leaking O-rings was directly after changing out the filters and leaving the old O-rings in place. The O-rings generally fail because they have become hard and no longer retain their round profile. That is why I always keep spare O-rings in stock. I store the O-rings in a Ziplock bag and in my air-conditioned home. We live in the tropical south and anything rubber perishes in no time if not sealed in an airtight container.When I change out the filters, I always put a thin coat of Vaseline or cooking oil on the O-rings before installation and a coat on the filter bowl threads. Lubricating the filter bowl threads works well. It stops the plastic threads binding on each other and makes it easier to loosen off as well.Review for: AppliaFit O-Rings Compatible with APEC O-Ring-HB for Big Blue, Compact Blue and Clear Water Filter Housings (4-Pack)

this o ring fit our whole house filter. the ring fit into the indent and made a good seal. make sure you use food grade lubricant like the one you use for hydration packs when you install the o ring.

real crap, i installed them on my big blue water treatment and it leaked worse than before, i tried to unscrew the unit and was never able to remove it.Called a plumber and he couldn't unscrew it either.End of story, it costed me over $500 to replace everything.This is truly crap and I would appreciate my money back !!!
