Hey all,

Hoping this is a good place to post this. I am looking for a check valve tri-clamp gasket to put on my serving tanks between my butterfly valve and the draft line. I cannot seem to find what I am looking for. I know they exist because I have used them in the past. The one that I have used that I liked was a hard gasket, I'm guessing PTFE, with a small hole in the center with a small plug and spring mechanism. If anyone can point me toward something like this that you are using or know of, that would be awesome.

This is the closest thing I've found, but it is much larger and would not sit in the smaller diameter fitting of the draft line.

Thanks in advance for any help!
