AN fittings all equal ?

[BR3W CITY]

I've got Early, Summit, Jegs, Fragola and a few Aeroquip fittings, and they all play pretty nice together. I even have a few copper JIC fittings that do alright with them (just can't be tightened down to the same level.

Thats how the Aeroquip and large companies get you; Aeroquip makes lots of the suuuper high end unusual fittings, the kind you don't need....right up until you do. Last thing you want is to find out 1 fitting is going to change the whole system. This is why when you open the $10k box-o-fittings on a race trailer, it tends to be FULLY stocked by 1 company, usually a Russel, Earls, or Aeroquip.
