Yeah, I think he means exactly the opposite.

How it working?

basically, just set the .tmp of some TTAN to one, easiest with the console (!set tmp ttan 1). Then it will block pressure without needing any full TTAN walls surrounding it. A real wall would be nice, but this will do.
Also remember that air goes on a 4x4 grid just like walls. And the pressure will be able to get into, but not out of, the 4x4 grid area the TTAN is in. So you have to make the area a little larger, like the lower right WIFI in my save.
Not exactly true, if you make a round bottle of 2px thick TTAN and fill it with pressure it will slowly leak out if you leave it for a while
