Re: CO2 reg meltdown
Here's a little plumbing experience for those who have never played with
tubing and its various connectors.
It's true that teflon tape will clog orifices in gas lines. It shreds
quite easily. Don't use it on gas lines, period.
As for connecting the tubing, if the tubing connects with a nut to the
fitting, that is, if the tubing has a nut on it that is held on by
either the tubing being flared or the presence of a brass sleeve (called
a ferrel) on the tubing, then there is no need to put any sealant of any
kind on the threads of the fitting as the flared tubing or ferrel is
what makes the seal. It's a metal to metal seal. Any sealant on the
threads will make no difference whatsoever. If the joint leaks, it will
leak out around the top of the nut where the tubing passes, with or
without thread sealant on the threads. Sometimes there will be a nut
with external threads held on by a flared end of the tube. Same thing,
metal to metal seal.
If one of these joints continues to leak, try painting a thin, and I
mean thin, coat of pipe sealant on the male side of the joint right
where the two metals meet. If that doesn't work, get a new fitting.
It's quite easy to test for leaks by spraying dish soap mixed with
water on the joint. If you get bubbles, you got leaks.
Thanks for this list! I love it!
