Just file this away in case you ever need it. The air bags on the Ridewell suspension coaches are connected using 1 inch diameter hoses and large 37 degree JIC fittings. They can be a problem to seal back up when changing air bags. Which leads to overtightening, which will be a pain if you ever need to remove the fitting again. I have learned this the hard way. 

I bought some of these. https://flaretite.com/collections/37-jic...ite-coated  as some an experiment. I had the opportunity to play with them today, and installed them on the air bag fittings. I intentionally moderately snugged the fitting nut. Bubble tight at 120 psi. 

Just thought I would pass it on. I had no idea these things existed.
