PolarStar 0-220psi Pressure Gauge – 25mm Dial

The PolarStar 0-220psi Pressure Gauge is a precision replacement component designed for PolarStar HPA systems. Whether you’re maintaining an existing MRS (Micro Regulation System) or upgrading GEN1 and GEN2 Micro Regulators, this gauge delivers accurate pressure reading across the full operating envelope.

Key Features

• 0-220psi operating range – covers standard airsoft HPA pressure windows

• Replacement-grade quality – maintains system integrity and safety
• Compact design – integrates seamlessly into existing setups

Real-World Use Cases

HPA players rely on accurate pressure monitoring to maintain consistent FPS across game days. A failed or missing gauge compromises your ability to dial in optimal performance. This replacement is ideal for rebuilding a damaged MRS, upgrading older Micro Reg generations, or maintaining a backup gauge for competitive milsim events. Skirmishers using PolarStar systems will appreciate the clarity and reliability of this component.

Technical Specifications

• Pressure range: 0–220 psi
• Dial size: 25mm
• Thread: 1/8 NPT
• Compatibility: PolarStar MRS, GEN1 Micro Reg, GEN2 Micro Reg

Compatibility & Upgrades

This gauge is a direct fit for all listed PolarStar regulators. If you’re upgrading from an older generation Micro Reg or replacing a damaged gauge on your MRS, installation is straightforward. Ensure your regulator uses 1/8 NPT threads before ordering. No additional tools or modifications are required.

UK Legal & Site Notes

As a pressure monitoring component, this gauge is not subject to UK airsoft import restrictions. All PolarStar HPA systems must comply with your site’s velocity and joule limits; accurate pressure reading helps you stay within permitted ranges. Always chrono before skirmishes to confirm FPS compliance.
