Aro R37121-600 Air Regulator 1/4 NPT 59 cfm 250 psi
A 1/4 NPT inline air regulator rated for 59 cfm at 250 psi with an integrated gauge and knob adjustment
- Delivers consistent airflow up to 59 cfm for pneumatic tools
- Handles supply pressure up to 250 psi for demanding applications
- Operates reliably up to 140 °F in harsh environments
- 1/4 in NPT ports integrate directly into standard air lines

1/4 NPT Air Regulator for Pneumatic Systems
This 1/4 NPT compressed air regulator manages line pressure for pneumatic tools and equipment. It suits maintenance crews and machine shops that need consistent downstream pressure. The aluminum body handles air service up to 250 psi maximum operating pressure. A pressure gauge is included for immediate monitoring.
Sustained Flow at 59 cfm with Gauge Feedback
Under continuous demand the unit passes up to 59 cfm while the knob adjustment holds the set pressure. The integrated gauge lets operators verify delivery without extra fittings. Rated to 140 degrees F, it maintains regulation during extended runs. Female NPT ports on both ends keep plumbing straightforward.
250 psi Maximum Operating Pressure Decides Fit
The 250 psi ceiling is the single figure that determines whether this regulator matches the system. Lines rated higher need a different part; lines rated lower work within this limit. No other specification overrides this pressure boundary for correct selection.

Questions about this item
How does this Aro R37121-600 regulator handle continuous 250 psi operation without overheating?
The regulator is rated for a maximum operating temperature of 140 degrees Fahrenheit and a maximum pressure of 250 psi, with an aluminum body that dissipates heat during sustained use.
What fittings are required to install this 1/4 NPT regulator into an existing air line?
The unit has female 1/4 inch NPT inlet and outlet ports, so male 1/4 NPT fittings or adapters are needed to connect it to the air line.
Will the 59 cfm flow capacity of this Series 1000 regulator restrict older tools that need higher volume?
Maximum flow is 59 cfm; tools requiring more air volume will see reduced performance, while tools within that limit will operate normally.
