Stewart Warner 855000-5 Aircraft Oil Pressure Gauge: A Detailed Analysis

The Stewart Warner 855000-5 Aircraft Oil Pressure Gauge (Alt P/N Q-21508-A Spl883002) is a widely used aviation instrument designed to monitor oil pressure in aircraft engines. In this analysis, we will discuss the key features, advantages, and disadvantages of this product.

1. Mechanical design with a 5-inch dial face

2. Calibrated for -65 F to 350 F (-54 C to 177 C) temperature range

3. Suitable for both piston and turbine engines

4. Brass construction with a chrome-plated dial

5. 0-100 psi (0-689 kPa) pressure range

6. Includes a 60-inch (152 cm) 1/8 NPT pressure hose

1. Robust and durable design: The brass construction and chrome-plated dial make the gauge resilient to the harsh aviation environment.

2. Wide temperature range: The gauge can operate in extreme temperatures, making it suitable for various aircraft applications.

3. Versatility: The gauge is suitable for both piston and turbine engines.

4. Easy installation: The 60-inch long hose simplifies the installation process.

1. Mechanical design: While the mechanical design offers simplicity and ruggedness, it may not provide the same level of accuracy as electronic gauges.

2. Limited pressure range: The 0-100 psi pressure range may not be sufficient for high-performance aircraft or engines with very high oil pressure requirements.

3. Requires periodic calibration: Since it is a mechanical gauge, the Stewart Warner 855000-5 may require more frequent calibration compared to electronic gauges.

The Stewart Warner 855000-5 Aircraft Oil Pressure Gauge provides a reliable and robust solution for monitoring oil pressure in various aircraft applications. Its wide temperature range, versatility, and easy installation make it an attractive option for many aviation professionals. However, its mechanical design, limited pressure range, and the need for periodic calibration may not appeal to those seeking the highest level of accuracy and convenience.

If you're looking for a simple, durable, and affordable oil pressure gauge for your aircraft, the Stewart Warner 855000-5 is an excellent choice. However, if you require a higher pressure range, greater accuracy, or an electronic design, you may want to explore other options in the market. Ultimately, your decision should be based on your specific aircraft needs, budget, and personal preferences.
