Those "Industrial" style (aka Milton couplers for the old garage-equipment
supplier who still makes them) aren't all that bad. Sure, the
Chinese/Japanese/Taiwanese/etc. copies are often junk, but brass Milton
couplers hold up and seal just fine. One of mine is occasionally a little
leaky now, but it's been in service since 1970. And I think it's just
loose, but maybe it actually needs its first new o-ring.
