Overview
The Norgren R08-300-RGMA is an inline pneumatic pressure regulator designed for compressed air treatment and regulation in industrial pneumatic systems. This brass regulator features a built-in gauge for real-time pressure monitoring, making it ideal for applications requiring visual feedback and stable outlet pressure control.
Key Features
- Integrated pressure gauge (0–160 PSI / 0–11 bar range) for direct readout
- Brass body construction for corrosion resistance and durability
- 3/8″ NPT port connections for standard compressed air piping
- Stable 150 PSI maximum outlet pressure setting
- Compact inline design for space-efficient installation
- Proven Norgren design for reliable performance in harsh industrial environments
