Silcone tubing and CO2

In my experience, the advantages of silicone tubing (soft (makes good
seal), stays flexible) are more important than any marginal gas loss.

I have tried pressurizing a long piece of hose and it holds its pressure
overnight, so I think the loss thru the wall is for our purposes
unmeasurable.
