3/8" Air Regulator with Gauge – 80 SCFM, 250 PSI Max, 5–125 PSI Range, Aluminum Body, 3-Position Locking Knob, Self-Relieving, Tamper-Proof Cap

The Arrow Pneumatic 3/8" Air Regulator with Gauge (Model RG-38A) offers precise pressure control and high airflow capacity in a compact, durable design. With an 80 SCFM flow rate and 250 PSI max inlet pressure, this regulator is engineered for demanding industrial applications that require reliability and accuracy.

The micro-finished brass valve seat ensures there is no reduced pressure creep, while the reinforced diaphragm delivers long-term stability and consistent output—even with frequent adjustments. The 3-position non-rising adjustment knob makes it easy to securely lock settings: pull to adjust, push to lock, or detach to prevent tampering.

This self-relieving regulator automatically vents excess downstream pressure for safer operation. The aluminum body offers superior durability, while the built-in gauge provides real-time system feedback. Designed for both inline and modular installations, it can also be easily panel mounted and comes with a tamper-proof cap for additional security.

With replaceable parts and a robust construction, the Arrow Pneumatic 3/8" regulator delivers the high-performance air pressure control professionals depend on—job after job.
