You might want to call them direct in San Antonio, TX

The shops in Phoenix are dealers....I have found that they usually dont stock squat and try to steer you to buy whatever they have.

There probably are other Aeroquip sources.....I bought from Vintage Air without shopping around. On page 68 of their catalog is the Aeroquip stuff. You need -6, -8, and -10 line... the fittings are not AN but the hose is AN sized.

Our first installation has held pressure for 3 years without having to be recharged....a record for home assmbled lines here!
