ARG20~40, Regulator w Built-in Pressure Gauge

The SMC ARG series modular air regulator comes with a handy built-in pressure gauge and backflow mechanism which enables reliable discharge of air pressure from outlet to inlet. 

Select the mounting angle depending on the piping direction. This series of pressure gauges is designed to resist revolving, even after the handle is operated. 

Please note that the ARG-B series has been names as a replacement for this ARG series.  While this ARG series has not been officially discontinued and some inventory may still be available, we recommend using the ARG-B series for any new applications.
