Description
The Wilkerson R18-03-F000 is a compact relieving-style air pressure regulator engineered for reliable, precise pressure control in demanding pneumatic and compressed-air systems. Built with a durable zinc body and a 3/8″ NPT port, this regulator is an ideal solution for industrial and commercial HVAC applications where space is limited but performance cannot be compromised.
Key Features
- Compact relieving regulator design — safely vents downstream pressure when set point is reduced
- Zinc body construction for corrosion resistance and long service life
- 3/8″ NPT port size for straightforward installation into standard pneumatic lines
- High flow capacity of 97 SCFM to support demanding air system requirements
- Wide adjustable output pressure range of 5–125 PSIG for versatile application use
- Maximum supply pressure rating of 300 PSIG for compatibility with high-pressure supply lines
- Two 1/4″ gauge ports for convenient upstream and downstream pressure monitoring

Application
The R18-03-F000 is well-suited for use in pneumatic control systems, air preparation assemblies, and compressed-air distribution networks found in commercial HVAC, industrial automation, and process control environments. The relieving design ensures that downstream pressure is automatically vented when the set pressure is lowered, preventing pressure buildup and protecting downstream equipment. The dual 1/4″ gauge ports allow technicians to easily monitor both supply and regulated pressures without additional fittings.
