Tronair KHC-3560 – Hydraulic Reservoir Coupling Kit for Select Embraer Aircraft

The Tronair KHC-3560 hydraulic reservoir coupling kit is designed to provide a secure, quick-disconnect interface when servicing aircraft hydraulic systems. It enables technicians to connect and disconnect hydraulic service equipment efficiently, minimizing fluid loss and contamination. This supports safer, cleaner, and more controlled hydraulic maintenance procedures. Quick-disconnect capability is especially valuable during frequent servicing or testing tasks.

The KHC-3560 coupling is designed for use with phosphate ester–based hydraulic fluids, which are commonly used in many aircraft hydraulic systems. Using the coupling with incompatible fluids may result in seal degradation or leaks. Always verify fluid compatibility before installation or use to maintain system integrity. Following manufacturer guidance helps prevent premature component failure.

Quick-disconnect couplings reduce the time required to connect hydraulic service equipment to the aircraft reservoir. They also limit fluid spillage during connection and disconnection, which improves cleanliness and reduces environmental and safety risks. This efficiency is especially beneficial in busy maintenance environments, where turnaround time is crucial. Cleaner connections also help protect sensitive hydraulic components.

The KHC-3560 is designed as a service interface component rather than a permanent modification to the aircraft. It is used during hydraulic servicing, testing, or maintenance activities and should be installed and removed according to approved procedures. Unauthorized or permanent modification of the coupling is not permitted and can void warranties.

The coupling kit includes JIC-style fittings that support common hydraulic servicing connections. These standardized fittings help ensure proper mating with compatible hoses and service equipment. Correct thread engagement and torque are essential to prevent leaks or damage. Using the specified fittings supports safe and repeatable hydraulic servicing.

Aircraft hydraulic systems are highly sensitive to contamination, which can lead to component wear or system malfunction. The KHC-3560 features a dust plug to protect the coupling when not in use, thereby helping to keep debris out of the hydraulic system. Proper use of protective caps and adherence to clean handling practices are essential. Maintaining contamination control extends system life and improves reliability.

Routine inspection is recommended to check seals, threads, and mating surfaces for wear or damage. Any signs of leakage, corrosion, or physical damage should be addressed before further use. Replacement parts should be sourced directly from Tronair to maintain compatibility and warranty coverage. Regular inspections support safe hydraulic servicing operations.

The KHC-3560 should not be modified without written approval from Tronair. Unauthorized modifications void the warranty and may introduce safety risks or system incompatibility. If a different configuration is required, it is best to consult with Tronair or an authorized distributor. Using OEM-approved components ensures compliance and reliability.

The expander included in the KHC-3560 kit is designed to support proper tubing engagement during hydraulic servicing. It helps ensure a secure and stable connection between service equipment and the aircraft hydraulic system. Proper use of the expander contributes to leak prevention and connection integrity. Each component in the kit plays a role in safe servicing.

By reducing fluid spray, leaks, and uncontrolled disconnections, the KHC-3560 helps create a safer working environment. Controlled hydraulic connections reduce exposure to high-pressure fluid and slippery surfaces. The quick-disconnect design also minimizes handling time during servicing. Safety-focused design is critical when working with aircraft hydraulic systems.

Tronair warrants the KHC-3560 to be free from manufacturing and material defects for one year from the date of shipment to the original customer. Replacement parts typically carry a shorter warranty period. Warranty coverage is contingent on proper use, maintenance, and the absence of unauthorized modifications. Always retain documentation for warranty support.

Using only Tronair OEM replacement parts ensures proper fit, material compatibility, and system performance. Non-OEM components may compromise sealing, fluid compatibility, or structural integrity. OEM parts also preserve warranty coverage and reduce liability risks. For critical hydraulic connections, using approved parts is essential for safety and compliance.
