couplings etc. that restrict the airflow, unless maximum flow is not
needed.

gauge to one 1/4" female gauge port and plug the other 1/4" female
port, or use it as a regulated outlet port.
5. Turning the adjusting screw clockwise increases the regulated pressure
and turning it counterclockwise decreases the regulated pressure.
6. Panel mount regulators require a 17/8" diameter hole and are mountable
on panels from 1/8" to 1/2" thick.
