What size PETG?

[Watashi]

I plan on buying my PETG from EKWB. I was curious about size PETG tubes I should get and why? (size in reference to inner and outer diameter)

It's the OD that matters since that is what the fittings will seal against, as for size it just depends, 16mm is pretty commonly used I find since it tends to fill out the system well visually where them smaller 12mm doesn't looks as proportional in larger more open cases.

Thank you. I'm going to go with 16mm I think I will like them better. Maybe in the future I'll go with the smaller OD however. I think they both have some pretty cool possibilities. I can see myself putting the smaller of the two in a more cramped case
