Hope I'm understanding your question....those two pieces stay screwed together....loosening or tightening it is what controls the air flow.
Yep, I knew that
If you're looking at the threads in the left pic....no...you can't use an ego threaded device on that seperate piece. I just tried it to make sure.
Exactly my question, so Thanks, would be a perfect solution to T3Ss and PTII minis on a MOD
I use these on nearly all my mods, not so much for air flow control, but as a means to protect the threads of my mods and since they are sealed, there is a certain amount of protection from juice getting down to the post in the mod.
That was the idea for my VTR
The air flow control is 510 threaded.
