Jet fuel transfer is a demanding application where hose selection is only part of the solution. The complete connection system also needs to provide reliable sealing, easy handling, and efficient connection and disconnection.
For an aviation project involving jet fuel transfer, CJan Fluid Technology Co., Ltd. recommended a combined solution of GGP Jet Fuel Composite Hose + DFCS Dry Disconnect Coupling based on the customer's operating conditions.
The solution was selected to address the customer's main requirements: jet fuel compatibility, 4-inch large-diameter transfer, up to 10 bar working pressure, reliable connection, reduced leakage risk, and convenient installation.
The customer works on aviation and aircraft-related projects. The hose assembly is intended for jet fuel transfer.
Because the application involves fuel handling, the customer was particularly concerned about the connection between the hose and the equipment.
The main requirements were:
Based on these requirements, CJan proposed a GGP composite hose combined with DFCS dry disconnect couplings.
| Item | Requirement |
|---|---|
| Industry | Aviation |
| Application | Aircraft / jet fuel transfer |
| Medium | Jet fuel |
| Temperature | Ambient |
| Working Pressure | Up to 10 bar |
| Hose Size | 4 inch |
| Connection Requirement | Reliable sealing, reduced leakage |
| Installation Requirement | Easy and convenient |
| Recommended Solution | GGP Composite Hose + DFCS Dry Disconnect Coupling |
For fuel transfer systems, the hose itself is not the only component that needs to be considered.
The connection points between the hose, equipment, and pipeline are also critical.
A connection system that is difficult to operate can result in:
For this reason, the customer required a connection solution that was not only secure but also convenient for field operation.
For the flexible transfer line, CJan recommended the GGP Jet Fuel Composite Hose.
GGP is designed for demanding fluid transfer applications where flexibility and chemical compatibility are important.
For this project, the 4-inch hose provides a flexible alternative to rigid piping for jet fuel transfer.
The flexible structure is particularly useful when the hose needs to be routed around equipment or moved during operation.
To complement the GGP hose, CJan recommended the DFCS Dry Disconnect Coupling.
A dry disconnect coupling is designed for applications where controlled connection and disconnection are important.
For jet fuel transfer, this can help address one of the customer's main concerns: reducing fluid leakage during connection and disconnection operations.
Quick connection and disconnection
The coupling design simplifies field operation and reduces the time required for hose installation and removal.
Reduced fluid spillage
The dry-disconnect design helps minimize the amount of fluid released when the connection is disconnected.
Convenient maintenance
The quick-connect design makes hose replacement and routine maintenance easier.
Suitable for demanding fluid transfer systems
The coupling can be integrated with an appropriate hose assembly according to the application requirements.
The customer did not simply need a fuel hose. They needed a complete flexible connection solution.
The two products address different parts of the application:
Main function:
Flexible jet fuel transfer
It provides the flexible section required for routing and fluid transportation.
Main function:
Quick and controlled connection/disconnection
It focuses on connection convenience and reducing leakage during operation.
Together, the two components create a more practical hose assembly for aviation fuel transfer applications.
The GGP composite hose is selected according to the jet fuel application and specified operating conditions.
The DFCS dry disconnect coupling helps control fluid release during connection and disconnection.
The flexible hose and quick-connect coupling simplify field installation compared with rigid piping arrangements.
The quick-disconnect design makes it easier to remove and replace the hose assembly when required.
The 4-inch hose size is suitable for applications requiring relatively high-volume fuel transfer.
Depending on the final system design and applicable standards, similar hose and coupling solutions can be considered for:
For each project, hose and coupling selection should be confirmed against the actual fuel specification, pressure, temperature, connection configuration, applicable aviation standards, and installation conditions.
CJan Fluid Technology Co., Ltd. provides hoses, tubing, couplings, and fluid connection solutions for demanding industrial applications.
Our product range includes:
CJan focuses on matching the hose and connection components to the customer's actual working conditions rather than selecting individual components separately.
For this aviation project, the application required a 4-inch hose for jet fuel transfer at ambient temperature and up to 10 bar, with particular attention to connection sealing and ease of installation.
Based on the application requirements, CJan recommended:
GGP Jet Fuel Composite Hose + DFCS Dry Disconnect Coupling
The combination provides a practical approach to flexible fuel transfer, convenient connection, easier maintenance, and reduced leakage risk during connection and disconnection.
For aviation fuel applications, selecting the hose and coupling as a complete assembly can help create a more reliable and easier-to-maintain transfer system.
