These are good to have

Stopped the leak on my cod tank, thank you!

Affordable and works. What more can you ask.

Replaced my seal for my co2 setup. Seals tightly.

I was not sure a hard washer like this would seal as good as the soft ones I have been using. I like the fact that these are not clear so I can easily see if they fall out. Sealed well and the co2 does not leak from the valve.
