BUSINESS SCOPE
Our quick connect fittings are made from high-quality synthetic materials, designed to be innovative, secure, and fast. They are ideal for a wide range of applications including fuel lines, oil vapor systems, water cooling, and air lines. These connectors are specifically tailored for automotive piping systems. The design and manufacturing process strictly follow SAE J2044-2009 standards, ensuring compatibility with liquid fuel and vapor or emission systems. If the product does not meet your needs, we can customize it according to your specifications. The plug-in and self-locking structure allows for easy and quick connection and disconnection. The required space for operation is minimal, just the width of a finger on both sides. This feature makes it possible to achieve high-density arrangements and increases your design flexibility.
The quick connector features a double sealing ring radial sealing structure. Modified rubber O-rings are used, which are suitable for various fluids and offer excellent resistance to aging, corrosion, and swelling. The outer O-rings are separated by an intermediate spacer ring. This ensures that there is no bonding between the two sealing rings, and the use of synthetic rubber O-rings improves mechanical properties and prevents aging. The sealing ring and spacer ring are securely fastened in the shell using an elastic clamping device, preventing issues such as ring falling or shifting. This guarantees a reliable seal.

The quick connector consists of a body, inner O-ring, outer O-ring, spacer ring, securing ring, and locking spring. When a mating tube end piece is inserted into the connector, the locking spring's elasticity helps to connect the two components. Pull back to ensure a complete connection. To repair or remove the connector, push the male connector and press the clip button, allowing the lock to expand, making it easy to pull out the connector. Note that SAE 30th heavy oil lubrication should be used before reseating.
