So many quick connectors. According to your scope of application. How can you answer this question? The quick connector can be divided into: quick connector for air, quick connector for oxygen fuel gas, quick connector for gas and liquid, quick connector for oil pressure, quick connector for inert gas, quick connector for cooling water temperature oil, and semiconductor quick connector.

    1. The type and temperature of the fluid (please select the quick connector of the body material and sealing material suitable for the type and temperature of the fluid) The suitable body material and sealing material are different according to the fluid. For example, the quick connector is air. Steel is recommended, but brass or stainless steel is recommended for water.

    2. The pressure of the liquid (please select the quick connector suitable for the pressure resistance of the fluid pressure). The pressure of the fluid is also the key to the selection of the quick connector. The quick coupling for hydraulic is formed between 5.0Mpa(51kgf/cm²)-68.6Mpa(700kgf/cm²), and the structure of the quick coupling is different according to the pressure resistance characteristics.

    3. The structure of the automatic switch valve (please select the quick connector of the valve structure suitable for piping). For the structure of the valve, there are two-way switch type, one-way switch type and two-way open type. In addition to the two-way switch type, fluid flows out of the piping during separation. So please pay attention.

    4. The use environment of the quick connector (please select a quick connector suitable for the structure and material of the use environment) Consider the type and body of the selected quick connector in combination with the humidity conditions of the use environment, the status of dust, and the use environment that is easy to corrode. Material, sealing material.

    5. The shape and size of the installation (please order the product after determining the final shape and size), please determine the model and material of the quick connector, and specify the assembly shape and size corresponding to the piping characteristics. Please note that the size is related to the fluid flow.
