This was really helpful! Thank you for the tip on using WD40 on the swivel... I could not figure out why my 90 degree fittings were leaking air from these spots

Did the bubbles go away after you sprayed your swivels with WD40?

@@buust1000hp no, my issue was user error with installing the fittings to the hose. If I remember correctly I was using too much lube

I just pumped air in with a tire inflator and checked every hour or so. I went from 120 psi to 80 psi in 1 hour, then 80 to 60 in the next hour.
