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.


There are a lot of options for very high temperature thread
sealants. Search
on this term in Mcmaster for example.

However, teflon is supposed to go up to 500 deg. F. I am not an
expert in
air compressors, but I would think if the output air is that hot,
something
else might be getting damaged.


How about sealant for EGR pipe and oxygen sensor threads? Never-Seez
perhaps?
