Tronair KHC-2173 Aircraft Engine Oil Coupling Kit

The Tronair KHC-2173 Engine Oil Quick-Disconnect Kit provides a reliable interface for servicing aircraft engine oil systems. Its primary function is to simplify oil transfer operations while preventing leaks and contamination. Allowing technicians to connect and disconnect fluid lines quickly supports efficiency and safety in routine engine maintenance.

The quick-disconnect design reduces downtime by allowing oil lines to be connected or removed in seconds without the need for tools. This minimizes the risk of spillage and ensures clean servicing procedures. For operators, this feature helps streamline workflow, making scheduled maintenance or troubleshooting faster and more efficient.

The kit includes three main components: a dust plug (N-2423-02), a tie wrap (H-1513), and a half coupling (N-2422-02). Each part is designed to work as an integrated system, ensuring durability and proper sealing during oil servicing.

The KHC-2173 is designed as a universal servicing tool compatible with a wide range of business, commercial, and military aircraft. Its utility lies in adapting to engine oil servicing applications that require quick disconnect couplings. Operators should always verify compatibility with their specific aircraft maintenance manuals before use.

The dust plug protects the coupling from contamination when not in use. By preventing dust, dirt, or foreign matter from entering the fluid path, it ensures the aircraft’s oil system remains free from harmful debris. This contributes to long-term reliability and helps extend the life of the engine oil system.

Tronair warrants the KHC-2173 kit to be free of manufacturing or material defects for one year from the date of shipment. Replacement parts, however, carry a shorter 90-day warranty. The warranty excludes normal maintenance items, parts covered by other manufacturers, and any products that have been misused, altered, or repaired without authorization.

The kit should be stored in a clean, dry environment to prevent contamination or corrosion. To protect the interior surfaces, the dust plug should always be inserted into the coupling when idle. Keeping the kit in a designated protective case or maintenance tool chest helps extend its service life.

This kit is designed specifically for engine oil servicing, and use with other fluids is not recommended unless explicitly approved by Tronair. Using the coupling with incompatible fluids may damage seals, compromise performance, or pose safety risks. Operators should follow the OEM’s specifications to ensure proper application.

OEM parts ensure that the coupling maintains its original fit, durability, and performance. Substituting with non-OEM parts could result in improper sealing, reduced reliability, and voided warranty coverage. For operators, sticking with genuine Tronair replacement components protects both the tool and the aircraft being serviced.
