I've ordered these 3 times now and they've always been the right size and included the lubricant for the seal. Piece of cake to install. Never leaked after replacement.

The seller description is inaccurate , does not fit Big Blue 4x20 too small for the filter system. Will not work.

I ordered these O rings for my Big Blue water filter casings as well as some from another vendor. These are not nearly as thick as the other brand. I hope when I use them they don't leak because they look like they are going to disappear into the casing groove. I would say get another brand that only give you two rings instead of three but are much thicker.

It’s very handy, and you don’t have to look for an outlet!

The diameter of the o-ring is smaller than original. Cleaned both grooves, lubed with silicone lube, inserted into both grooves. Tighten housing and leaks. Rechecked housing, still leaking. Installed older o-rings and no leaks. DON'T PURCHASE

I found these to work excellent as replacement oring for my heavy duty whole house filter housing. The package also came with a small dispenser pack of Vaseline to spread on the oring before reassembling the filter housing. The jelly holds the oring in the groove of the lower part of the housing and provides lubricant while screwing the filter bottom into the housing.
