Yes, the HDA22700 fittings are hi flo fittings.
The HDA22700 kit should work with any standard air hose with 1/4" male threads on the ends.
The info on these states they are industrial type fittings producing 25% increase in flow. I don't know what they are gauging that by or to, however, I am using these fittings all day long at 165 PSi and have had no issues with them. They stay on strong and no leaks.
