Tronair 14-6884-6000 High-Pressure Aircraft Strut Pressure Gauge, 0 to 3,000 PSI

The Tronair 14-6884-6000 is used to service, verify, and adjust nitrogen-pressurized landing gear struts on a wide range of aircraft. This high-pressure gauge enables technicians to accurately measure strut pressure during maintenance procedures, ensuring proper extension, shock absorption, and ground handling performance. Its design supports precise nitrogen servicing operations while helping maintain compliance with aircraft maintenance manuals.

The maximum operating pressure for the Tronair 14-6884-6000 is 3,000 PSI (207 bar). This capacity makes it suitable for high-pressure strut servicing applications on most business aircraft, regional aircraft, and some military platforms. Exceeding this pressure limit can damage the gauge or compromise operator safety, so proper regulator use is essential.

The gauge is designed for use with high-pressure nitrogen systems only and should not be used with oxygen or any other gas. It connects using standard high-pressure fittings and works with most aviation-grade nitrogen regulators. Always confirm compatibility with your Aircraft Maintenance Manual (AMM) and regulator model before servicing.

Yes. The pressure gauge must be calibrated annually or more frequently if dictated by your organization’s quality standards. Calibration ensures measurement accuracy during nitrogen strut servicing, which is critical for maintaining landing gear performance. Certificates of calibration are supplied with the unit at the time of shipment.

No. Tronair explicitly states that the gauge assembly is not Skydrol-resistant and should not be exposed to Skydrol-based hydraulic fluids. To avoid damage, keep the tool clear of hydraulic service areas where contamination may occur. If Skydrol exposure happens, clean the gauge immediately following approved maintenance procedures.

Yes. The gauge assembly includes an integrated air bleed valve (K-4494), which allows technicians to safely purge excess nitrogen during servicing. Bleeding trapped gas ensures accurate readings and prevents sudden pressure release when disconnecting the unit. This feature provides both safety and precision in servicing.

No. The manual warns that this gauge should not be used on low-pressure nitrogen systems, as its high-pressure design may damage sensitive components. Using the wrong servicing tool can also create safety hazards or result in incorrect strut extension. Always verify the pressure class for the system you are servicing.

Routine maintenance involves keeping the gauge assembly clean, dry, and free from contaminants, especially around the fittings and valves. The manual emphasizes that nitrogen equipment must be kept clean at all times to prevent damage or unsafe operation. If any part of the gauge assembly appears damaged or contaminated, it should be serviced or replaced by a qualified technician.

Yes. The included box/case (Z-3830-03) provides protection for the gauge assembly during transportation and storage. Using the case helps prevent accidental shock, contamination, or damage to the fittings.

No. Tronair states that the product cannot be modified without written approval, and any unauthorized modification immediately voids all warranties and releases the manufacturer from liability. Always use OEM parts and accessories to maintain safety and tool integrity.

Yes. PJi provides a wide selection of OEM replacement components, including gauges, boots, connectors, hoses, and high-pressure fittings. Replacement parts carry a 90-day warranty. Using only Tronair replacement parts ensures proper fit and safe operation.

Yes. The Declaration of Conformity in Appendix II of the Operations Manual confirms compliance with European Community Machinery and Pressure Equipment Directives, including 2006/42/EC and 2014/68/EU. This makes the tool suitable for aviation operators worldwide who require CE-marked equipment.

This gauge is approved for use with nitrogen only. It should never be used with oxygen or mixed gases, which can create extreme safety hazards. Verifying gas purity is a crucial step before servicing a strut.

Accurate pressure readings ensure proper strut extension, shock absorption, and taxi performance, directly affecting ride quality and landing gear longevity. Incorrect nitrogen pressure can lead to excessive tire wear, compromised handling, or structural stress on the landing gear. Using a calibrated, high-quality gauge, such as the Tronair 14-6884-6000, helps maintain consistent and safe aircraft operation.
