I’m trying to use the 4" o-ring flange on 4" tubes that are slightly larger than the standard acrylic tubes. The tubes measure 4.032" from what I can tell. The result is that they don’t seal up at all. Can I up-size the o-ring from the standard 238 o-ring to something larger to get it to seal? I’ve been looking at the o-ring calculators and it looks like the M4x92 might work. Is that correct? Or are there other issues that might come up that might cause this to not work?
Thanks!
