 I could see the O-ring contributing if it thought there was a leak here, but typically an O-ring will create not a 457, it'll be a smaller leak. It'll be less than a 20,000th of an inch vacuum. And you're smoking this? I haven't yet. Okay. Remember, smoke creates, what do you got, a smoke machine, half a PSI? Yeah, something like that. Yeah. Sometimes smoke expands the O-ring.
