Swiss torch hose

Hello to all:

I have a question for the Swiss torch users. I have one and love it
but the only hoses I could find that were small enough to slip over
the barb connection on the torch head is the clear plastic tubing.
Since I’m using propane and have been following the thread how these
are not safe to use for propane, can someone help me to find what I
should be using? I seem to recall that when I was trying to find the
proper hosing none of the American versions fit the barb. Thank you!
