Leak testing the control bottle with positive pressure

[EliotBR (Eliot)]

Hi @Jhans,

I don’t expect we have hard numbers on this, as our current enclosures are designed only for negative pressure and don’t have a positive pressure rating. I’ve asked our design engineers if they have an indicative number where the end-caps may push out, and will get back to you with the response

If it’s helpful, previous mentions of “positive pressure” have specified “a bit” or “a slight positive pressure”, and the only quantitative results I could find (from a community member) said

@corndog

maybe just a few pounds so it’s not enough to blow off the end caps and either dunk it or use soapy water.

The following comment may also be useful to avoid the vacuum plug coming out when positive pressure is applied:

@RogueWave, I took a vacuum cap, drilled a hole through it. Tapped, and threaded a fitting in to it so I can put positive pressure without blowing the vacuum plug out all of the time as it threads in. [Vacuum cap]
