How does quick release coupling work?

They are designed with a spring loaded ball latching mechanism which automatically locks the two halves of the fitting together when they are pushed together. When the releasing sleeve (knurled for easy handling) is pulled back, the internal end and external ends quickly disengage from each other.

Do quick connects reduce air flow?

When air is released at disconnect, the ball prevents the air from escaping rapidly. A disadvantage of this design is restricted airflow during use. An alternative is to select a zero-pressure, quick-connect coupling. This design automatically depressurizes the downstream air volume as it shuts off the upstream supply.

Do quick disconnects restrict flow?

Yes but only with a 100’section of hose and never with quick connects except the ones from the ball valve and the ones on this one section of hose.
