Overview
The Wilkerson R03-02-L00 is a no-gauge, compact air regulator designed for pneumatic systems requiring space-efficient pressure regulation. With a 1/4″ NPT connection, this mini regulator is ideal for point-of-use applications where larger regulators cannot fit. The R03-02-L00 maintains consistent outlet pressure across varying inlet conditions, making it a reliable choice for controls engineers and maintenance technicians working with compressed air systems.
Key Features
- Compact Design: Mini regulator footprint fits tight installation spaces
- 1/4″ NPT Ports: Standard female NPT connections on inlet and outlet
- No Gauge Configuration: Streamlined unit without dial indicator for weight and cost savings
- Adjustable Pressure: Knob adjustment mechanism for quick outlet pressure tuning
- Zinc Body Construction: Durable housing for industrial pneumatic environments
- Wide Inlet Rating: Rated for 300 PSI maximum inlet pressure capacity
