Re: gas permeability of silicone tubing

[Jennifer Glover <jglover at autometric_com>]

What I was told when I was assembling my CO2 system was that normal air tubing will
get brittle and ruined by the CO2 gas traveling through it.  The silicone tubing was
referred to me as a better choice because it takes the direct gas better than the
other plastic hose.  I am not sure if this isn't like teflon tape, where some people
use it and others don't.  The tubing was pretty cheap, so I didn't really care.
