Genuine AirTAC piston pressure regulator, order code SDR20008L3G from the SDR range. The options this code selects are decoded below; series data follow the official AirTAC catalog.
With G thread on its 1/4 port, SDR20008L3G pairs the low-pressure L regulating range of 0.03-0.4 MPa with a bar-scaled gauge, the scale the catalog ties by default to the G-thread option (psi goes with NPT, MPa with PT).
As an SDR200 it is a compact piston back-pressure regulator whose stable, low-cost output suits circuits that do not need high regulating accuracy. This code includes the bracket, handles air at up to 1.0 MPa (145 psi), is proof rated at 1.5 MPa (215 psi) and operates from -20 to +70 C.

Pick SDR20008L3G when the piping is G-threaded and the set pressure stays under 0.4 MPa. SDR20008L2T is the NPT twin with a psi gauge, SDR200083G is the G1/4 standard-range version regulating up to 0.9 MPa, and SDR20006L3G steps the port down to 1/8. Replacing the thread letter with T gives NPT and with blank gives PT; option N in the gauge position removes the gauge, option J removes the bracket.
Regulate air on G1/4 piping where set pressures stay below 0.4 MPa and the bar gauge reads the same scale as the rest of the control panel.
Set low clamping or blow-off pressure for fragile cartons, film wraps and labels at warehouse and end-of-line stations using the 0.03-0.4 MPa band.
Feed stable low-pressure air to small process or coating stations that need dependable output but not fine regulating accuracy.
G1/4 port, low-pressure L regulating range 0.03-0.4 MPa, bar-scaled gauge included, bracket included, maximum pressure 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi), fluid air, temperature -20 to +70 C.
The catalog pairs gauge scales with threads by default: MPa is standard with PT, psi with NPT and bar with G. SDR20008L3G combines the G1/4 port with the bar scale, so readouts match bar-based panels; the L code keeps regulation in the 0.03-0.4 MPa window.
