## Summary description

Proline Tools 66383. Maximum inlet pressure: 12 bar. Quantity per pack: 1 pc(s)

## Long description

Proline 66383 is a pressure regulator with an integrated gauge and a 1/4" connection designed to control compressed air or gas pressure in pneumatic systems. The unit provides visual pressure monitoring through the built-in manometer and enables precise adjustment of outlet pressure. It is intended for use in workshop air lines, spray equipment, and pneumatic tools that require stable regulated pressure.
Advantages
The regulator combines a compact mechanical design with an easy-to-read analog gauge, enabling quick visual confirmation of working pressure. Its 1/4" connection ensures compatibility with common pneumatic fittings and hoses. The adjustment knob permits fine control of downstream pressure while the robust housing provides resistance to workshop conditions. The integrated gauge reduces the need for separate measurement devices and simplifies installation.
Suitable for
 Workshop compressed air distribution lines
 Pneumatic hand tools and air-driven equipment
 Laboratory or light industrial pneumatic setups
Key specifications
 Connection size: 1/4"
 Integrated analog pressure gauge for visual monitoring
 Adjustable outlet pressure control via rotary knob
 Compact mechanical regulator body suitable for inline installation
 Materials designed for compressed air and compatible gases
How to use
Install the regulator inline on the compressed air hose or pipe using the 1/4" fittings, ensuring correct thread engagement and a leak-tight connection. With the input pressure present, use the adjustment knob to set the desired outlet pressure while observing the integrated gauge. Perform adjustments gradually and confirm stable pressure under the intended load conditions. Regularly check the gauge and connections for leaks or wear and replace components if accuracy or sealing degrades.
Usage recommendations
Use appropriate thread sealant or PTFE tape on fittings to prevent leaks, and isolate the regulator from high particulate or liquid contamination by installing upstream filtration. Avoid exposure to corrosive chemicals and observe the maximum recommended inlet pressures for pneumatic equipment. Periodic inspection of the gauge and mechanical parts helps maintain reliable pressure control.
