Klutch Mini Air Regulator - 1/4in. Item# 48571
Is one of the two Included 1/8in. ports for installing pressure gauges for the inlet pressure and one for the outlet pressure or are they both for the outlet pressure? Also what is the minimum pressure setting?1 answer-
KlutchExpert13· 9 years ago
There are two 1/8" ports for the convenience of installing a gauge on either port depending where the air regulator is placed. The gauge would only show the pressure in the line after the regulator. The minimal pressures setting are 7 psi.
