Aro R37341-600 Air Regulator
The Aro R37341-600 is a compressed air regulator built for heavy-duty pneumatic systems. It controls line pressure for tools and equipment that demand consistent delivery up to 210 cfm. The 1/2 inch NPT female ports integrate directly into existing air lines. Aluminium body construction and a Series 2000 rating suit industrial and automotive workshop environments.
Thermals noise and power draw
Maximum operating temperature reaches 140 degrees F under continuous flow. The acetal adjustment knob remains cool to the touch during normal regulation. No electrical power is required for operation, eliminating heat from a motor or solenoid. Silent mechanical regulation adds no audible noise to the compressor or tool exhaust.
Build fit and freedoms
Female NPT threads on both inlet and outlet allow straight pipe or hose connections without adapters. The 2 3/4 inch overall width fits tight manifold spacing between other components. An included pressure gauge removes the need for a separate monitoring port. The 250 psi rating frees the installer from derating downstream fittings or hoses.

Questions about this item
How do I install the Aro R37341-600 regulator on a 1/2 NPT air line, and what step is often missed?
Thread the female 1/2 NPT inlet and outlet onto the line using pipe sealant on male threads only, then set the knob to zero before pressurising — skipping the zero-set causes the gauge to read high.
What maintenance or replacement will the Aro R37341-600 need over time?
The acetal adjustment knob and internal seals wear first; inspect for air leaks at the knob stem and gauge port annually, and replace the regulator if pressure drift exceeds 5 psi at 210 cfm flow.
What limit appears first when the Aro R37341-600 runs continuously at high flow?
At 210 cfm the 250 psi maximum operating pressure is reached before the 140 °F temperature limit, so pressure relief or downstream demand must be managed to stay below 250 psi.
