How to use Swagelok tube fittings

This is very interesting.

I see it as a definite fix for the breakage-prone "JBJ" bubble counters and it is certainly more aesthetically pleasing.

My only question is, how do you count bubbles for CO2 levels using this method?

Thanks for the feedback. I'm glad the thread was helpful!

Gerry,

I think these tube adapters with external bubble counters are still the way to go. Mine have been holding up extremely well with the ADA pressure resistant tubing, too.

Hi all,

Please note that my tube fittings have been in use on both my units for well over 1 year now and have never had an issue with them at all.

One of my better decisions to ask Matt to incorporate these in my build...

According to the norcal swagelok blog you do not need to replace the ferrules each time.

Skill: Tube fitting assembly, one inch and under

That is interesting. I reuse the nuts, but I have never reused the ferrules. They get pretty smashed up. Good to know you can disconnect the tube from the adapter housing and reinstall the same tubing, etc. You have to replace the ferrules when you want to replace your CO2 tubing, though. ADA recommends you replace your pressure resistant tubing once a year to prevent leaks. It's virtually impossible to remove the ferrules once they are clamped onto the tube insert. Just makes sense to replace the ferrules, the tubing insert, and the tubing all at the same time.
