Genuine AirTAC piston pressure regulator, order code SDR20008L2T from the SDR range. The options this code selects are decoded below; series data follow the official AirTAC catalog.
SDR20008L2T builds an AirTAC SDR200 piston back-pressure regulator around three ordering choices: the 1/4 port cut as NPT thread (code T), the low-pressure L type and a psi-scaled gauge. Its L range spans 0.03-0.4 MPa, so it targets circuits whose set pressure never approaches the 0.9 MPa ceiling of the standard version.
The simple piston structure keeps output pressure stable in a small, cost-effective body that is easy to install, and this code includes the mounting bracket. Maximum operating pressure is 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi), with air as the fluid from -20 to +70 C.

Choose SDR20008L2T when the line is NPT-threaded, the working pressure stays low and a psi readout matters. SDR20008L3G is the same low-pressure regulator but on G1/4 with a bar gauge; SDR200082T is the standard-range sibling reaching 0.9 MPa; SDR20006L2T shrinks the port to 1/8. Leaving the thread letter blank gives PT, option N removes the gauge and option J removes the bracket.
Supply air anywhere in the 0.03-0.4 MPa band to lab fixtures or leak-test stations, with a psi gauge that matches the instruments on the bench.
Feed regulated air into NPT1/4 piping on packaging or assembly machines whose set points sit well below the 0.9 MPa standard-type ceiling.
Hold a steady pilot pressure on air-piloted valves and small actuators, where the piston design gives stable output without high regulating accuracy.
SDR200 piston pressure regulator, NPT1/4 port, low-pressure L regulating range 0.03-0.4 MPa, psi-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.
If every set pressure stays below 0.4 MPa, the L range of 0.03-0.4 MPa fits and starts lower than the 0.05 MPa floor of the standard type; circuits that must regulate up to 0.9 MPa need the standard version. Supply pressure must stay within the 1.0 MPa (145 psi) maximum.
