Tronair 14-6895-6000 Aircraft Strut Pressure Gauge, 0 to 1,500 PSI

The Tronair 14-6895-6000 aircraft strut pressure gauge is used during nitrogen servicing of landing gear struts. It allows technicians to accurately measure and adjust strut pressure in accordance with the Aircraft Maintenance Manual (AMM). Proper strut pressure ensures correct aircraft stance, shock absorption, and ground handling performance. Maintaining accurate nitrogen pressure is essential for both safety and structural integrity.

No. The manual clearly states that this gauge assembly is designed for use with nitrogen only and must not be used with oxygen or other gases. Using the wrong gas can create serious safety hazards and equipment damage. Nitrogen is chemically stable and non-flammable, making it suitable for aircraft strut servicing applications. Always verify gas compatibility before connecting the system.

The manual specifies that the inlet pressure must not exceed 1,500 PSI during operation. Exceeding this pressure limit can result in gauge damage or hazardous system failure. Although the assembly has a maximum operating capability of 3,000 PSI (as noted in the parts list section), technicians must follow the stated 1,500 PSI operating guidance for safe aircraft strut servicing. Always follow aircraft and equipment limitations.

The pressure gauge should be calibrated annually or as required by the operator’s quality system. Calibration intervals may vary depending on regulatory or internal maintenance standards. Accurate calibration ensures reliable strut pressure readings during nitrogen servicing. Maintaining certification records supports compliance with aviation maintenance documentation requirements.

No. The manual explicitly states that modifications without written approval from Tronair will void all warranties. Only Tronair OEM replacement parts should be used to maintain performance and safety integrity. Unauthorized alterations can compromise pressure accuracy and structural safety. Always consult Tronair before attempting any repairs.

This equipment must be operated only by trained and qualified personnel. Nitrogen under pressure stores significant energy and can pose hazards if mishandled. The manual emphasizes ensuring all valves are in the closed position before connection and warns against using the gauge on low-pressure nitrogen systems. Following approved procedures helps prevent injury and equipment damage.

No. This gauge assembly is not resistant to phosphate ester fluids. Exposure to incompatible fluids can damage seals and internal components. Technicians should ensure that only approved nitrogen servicing procedures are followed. Keeping the equipment clean and free from contaminants is critical.

Correct nitrogen strut pressure supports proper landing gear extension, taxi stability, and shock absorption during landing. Under- or over-pressurized struts can affect aircraft stance, braking efficiency, and tire wear. Using a calibrated aircraft strut pressure gauge ensures accurate adjustment. Routine strut pressure checks are a vital part of preventive maintenance programs.

After servicing, any excess nitrogen in the gauges and lines should be safely bled off using the air bleeder valve. This prevents high-pressure gas from becoming trapped in the system. Controlled depressurization enhances technician safety and protects internal components. Proper disassembly procedures should always follow the AMM and the gauge manual.

Tronair warrants the product against manufacturing or material defects for one year from the date of shipment to the original customer. The warranty covers repair or replacement of defective components but excludes normal maintenance parts. Replacement parts carry a 90-day warranty from the date of shipment. Unauthorized modifications or misuse will void warranty protection.
