How to choose a quick connector fitting

So many quick connectors. Depending on your scope of application. How do you answer this question? Quick connectors can be divided into: quick connectors for air, quick connectors for oxyfuel gas, quick connectors for gas-liquid sharing, quick connectors for oil pressure, quick connectors for use, quick connectors for cooling water and warm oil, and semiconductor quick connectors.

1. Type and temperature of the fluid (please select the quick connector of the body material and sealing material that is suitable for the type and temperature of the fluid) The suitable body material and sealing material are different depending on the fluid. For example, the quick connector is air. Steel is recommended. Brass or stainless steel is used for water.

2 The pressure of the liquid (please select a quick connector suitable for the pressure resistance of the fluid pressure) The pressure of the fluid is also the key to selecting a quick connector. Hydraulic quick couplers are serialized between 5.0Mpa (51kgf / cm²) and 68.6Mpa (700kgf / cm²). Corresponding to pressure resistance characteristics, the structure of quick couplers is also different.

3. The structure of the automatic opening and closing valve (please select the quick connector of the valve structure suitable for piping use) 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 pipe during separation. So please pay attention. 4. The use environment of the quick connector (please choose 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, dust conditions, and easy to corrode use environment Material, sealing material.
5. Installation shape and size (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 characteristics of the piping.
