OK, so you tried the propane torch... Were you able to get to a robust cherry red? If not, you might need a 'turbo torch'.
The Silfos doesn't need flux, but the parts still need to be clean. Did you wire brush or sand the surfaces you were brazing?

I used this torch,
Inside the tip, it has vanes in a swirl configuration, so it might already be a type of 'turbo torch'.
At first, I had the gas too low and it didn't work at all. So, I cranked up the flow and got better heating.
But it was very hard to keep it hot enough to have flow for more than
a second or two. Move the flame around to the other side, even a little
and the flow 1/4" away was gone. Turned solid. Didn't get any cherry red at all.
But, I had the garage door open and there may have been too much outdoor light to see the glow.
Maybe I should try again and just keep the heat going for an extra 5 minutes or until it goes cherry??
I did clean the connections beforehand, but perhaps I didn't do a good enough job.?.
My cleaner (unlike this one) is getting a bit old..
