when I worked at the rock quary, those reusable "repair" fittings were a big NO NO.
I have always been told to stay away from them. dont know why?
I used to buy alot of hydraulic lines (3/8) from boeing surplus and they had those ends on them. I still have a bunch of them in my fitting drawer. they were on 4000psi 3/8 gates hose most of the time.
nobody else seems to have had a problem here, though:eeek: I dont know why the boss hated them so much.
