300 Psi Pressure Gauge

The AUTOMETER 300 PSI Pressure Gauge (Part Number 5423) is a mechanical analog instrument designed for direct pressure monitoring in hydraulic, pneumatic, and fluid systems. This gauge is essential for equipment diagnostics, maintenance, and operational safety across various applications, including industrial and automotive settings.

Featuring a 2-5/8 inch diameter, this gauge delivers accurate real-time readings across a 0–300 psi range. Its liquid-filled design protects internal components from vibration, shock, and environmental contamination, making it ideal for field conditions where equipment may be subject to rough handling and variable temperatures.

This pressure gauge is particularly valuable for mechanics, hydraulic technicians, and equipment operators who require direct, immediate pressure feedback. Its 1/8 inch NPT port allows for straightforward integration into existing pressure circuits, ensuring compatibility with standard hydraulic fittings.
