Perfect fit
Fits in the Culligan gravity filter upper stage holes perfectly. Excellent quality strong plastic and silicone seals for both sides. No leaks and easy to use /install. No weird smells or taste. Worth the price.

Great for ProOne gravity filter
These worked great in my ProOne gravity filter. Stops water from leaking though!

fits and works fine
Fits perfectly for our Berkey falter filter system. It was pretty easy to install, just make sure you place the screw part straight on the bolt, otherwise you can not tighten it. No leakage detected, and I guess the value for the money is okay, I think they were pretty pricy for 2 little plastic stoppers.

Improves the quality of filter
They make a good seal for the supply portion of the Berkey. The rubber plugs that came with it were deteriorating and left residue in water.

Worth it.
Easy to install and much better than the old rubber corks. Not sure why I waited so long to get them.
