SAE7.89 High Pressure Automobile Fuel Line Fittings for Dongfeng Truck

 Material Of Quick Connector 2. Design and Production
Innovative, secure, and quick to use. Our quick connect fittings made of synthetic materials are suitable for most media-carrying lines. Whether it's fuel, oil vapor, water cooling, or air carrying lines, we offer the ideal means of connection. These quick connectors are specially suited to being matched with the automotive pipe system.
The design and production of quick connectors strictly adhere to SAE J2044-2009 Quick Connect Coupling specifications for liquid fuel and vapor or emissions systems. If the product does not meet customer needs, we can design and manufacture according to your requirements. The plug-in and self-locking structure enables faster and easier connection and disconnection. The space required for the operation is only the width of a finger on both sides. These features ensure that quick connectors can be densely arranged, increasing customer design flexibility.

3. Security of Quick Connector
Quick connectors feature a double sealing ring radial sealing structure, using modified rubber O-rings. These are mainly for fluid physics and chemistry, custom, anti-aging, corrosion resistance, and swelling. Outer O-rings are separated by an intermediate spacer ring. Corresponding space on the two sealing rings ensures that no rubber substrate bonding occurs. The outer synthetic rubber O-rings used increase mechanical properties, preventing aging. Sealing rings and spacer rings are securely fastened in the shell via an outer elastic clamping device, ensuring no phenomena such as ring falls or shifts occur. Great seal security is guaranteed.

4. Working Environment of Quick Connector
Gasoline and diesel fuel delivery systems, ethanol, methanol, or natural gas delivery systems, or their vapor venting or evaporative emission control systems.
 
5.Quick Connector Advantages
· Fast assembly without tools → time and cost reduction
· Robot assembly possible → automated processes
· Compact building method → employment in extremely close installation conditions possible
· Integrated seal → optimal tightness

6. Quick Connector Applications in the Automotive Industry
Can be used to make both line-to-line or line-to-equipment connections.
· Fuel feed / return lines
· Tank breathing
· Ventilation lines
· Oil cooler lines
· Vacuum control lines

7. The Type of Quick Connector
8. Connect & Disconnect Operation Method of Quick Connector
Quick connector is made up of body, in O-ring, out O-ring, spacer ring, securing ring, and locking spring. When a mating tube end piece inserts the connector, as the locking spring has certain elasticity, tie clip fastener to connect two connectors together, and then pull back to assure complete connection. Repair or remove the quick connector is different. First advance push the male connector and press the clip button, lock expansion, you can easily pull out the connector; please note, SAE 30th heavy oil lubrication should be used before reseat.
