Anything better than PTFE/Teflon for high temperatures?

Just go dry or what? High temperature compressor output line... the
hose is bellows with braid over it.



BIG PROBLEM ON THE HORIZON!!! I did exactly what you are talking about
and the temp from the output of the compressor was too high for the
braid covered hose! The hose under the SS braid disintegrated. DON'T
DO IT!

Hi, Tom, thanks for the warning.

This stuff is 300-series stainless on the inside too- no rubber. It's
crinkled like a bellows so it's flexible and braided with stainless
braid on the outside. It's not particularly cheap, but not insane.

I've used similar stuff at work to transport liquid helium. But
it had two bellows -- one inside the other, and the space between them
was evacuated to maximize insulation. Think of it as a long, flexible
Dewar. :-)

But I have one short run of the what you are describing, which I
intend to use to decouple vibration on a compressor from the pipes in
the shop.

Enjoy,
DoN.
