I used some welding gloves to hold the fitting and just pushed on the nylon air brake hose. Once everything was cool it was solid as a rock and has been working for over 20k now with no issues. I can;t recall what the air brake line cost but I know it was very cheap and I can get it anytime I need. The only thing it that its not clear.
