Something’s wet, isn’t it?
Sniff sniff… sniff sniff… Metal rubber?
After gripping it for a few days… it seems to be seeping a bit.
I’m not sure if we can check it with air, but I made something like this.
Let me run a quick test.

I mounted an air valve (excess inventory) that was lying around.
For sustained pressure retention, an air valve is the way to go.

I welded it solid to the union.
I’ll check it when I get a chance. Nothing ever goes smoothly in this world…
