air system must have a pressure rating
higher than or equal to the 200 psi for
two-stage compressors or 150 psi for sin-

setting. Incorrect selection and installa-
tion of any tube, pipe or hose could result
in bursting and injury. Connect piping sys-
tem to tank using the same size fitting as
the discharge port.
INSTALLING A SHUT-OFF VALVE
A shut-off valve should be installed on
the discharge port of the tank to control
the air flow out of the tank. The valve
should be located between the tank and
the piping system.
Never install a
