Structural classification
Opening and closing at both ends
When not connected: When the collar of the parent body moves to the other end, the stainless steel ball automatically rolls outward, and the sub body is disconnected due to the joint action of the parent body and the sub body valve spring force. The valves of the sub body and the parent body are closed respectively, instantly blocking fluid flow.
When connecting: When the sub body is inserted into the mother body, the collar returns to its original position under the action of the spring, and the steel ball rolls to lock the sub body tightly connected. At the same time, the valves of the mother body and the sub body push each other open, allowing fluid flow. The O-ring can completely block fluid leakage.
Open at both ends
Not linked: When the collar of the parent body is pushed to the other end, the steel ball automatically rolls outward, so the daughter body is removed; Due to the absence of valves in both the daughter and mother bodies, fluid flows outward.
When linking: When the sub body is inserted into the mother body, the collar is pushed to the previous position by the force of its spring, causing the steel ball to lock and fluid to flow. The O-ring in it prevents liquid leakage
Single-channel opening and closing
Not linked: When the collar of the parent body moves to the other end, the stainless steel ball automatically rolls outward, and the daughter body is bounced open by the reaction force of the valve spring, and the valve can automatically close to block fluid flow.
When connecting: When the sub body is inserted into the side of the mother body with a collar, the valve is opened, causing fluid flow. The gasket is pushed back to its original position by the force of the spring, and the stainless steel ball locks to ensure the sub/mother body connection. The gasket inside can completely block fluid leakage.

function
1. Time and effort saving: When disconnecting and connecting oil circuits through quick couplings, the action is simple, saving time and manpower.
2. Fuel saving: When the oil circuit is broken, the one-way valve on the quick connector can seal the oil circuit, preventing oil from flowing out and avoiding loss of oil and pressure.
3. Environmental protection: When the quick connector is broken or connected, the oil will not leak, protecting the environment.
4. Equipment is divided into small parts for easy transportation: Large equipment or hydraulic tools that require portability can be disassembled and transported using quick couplings, and then assembled and used at the destination.
5. Economy: All of the above advantages have created economic value for customers.
Selected
1. The type and temperature of the fluid (please select the appropriate type and temperature of the fluid, the material of the body, and the quick connector of the sealing material)
The suitable body material and sealing material vary depending on the fluid. For example, the quick connector is made of air. I recommend steel, but if it's water, choose brass or stainless steel.
2. The pressure of the liquid (please select a quick connector with pressure resistance suitable for the fluid pressure)
The pressure of the fluid is also the key to selecting a quick connector. The quick couplings used for hydraulic pressure are serialized between 5.0Mpa (51kgf/cm²) and 68.6Mpa (700kgf/cm²), and the structure of the quick couplings is also different according to their pressure resistance characteristics.
3. Construction of Automatic Valve (Please select a quick connector suitable for piping purposes)
For the construction of valves, there are two-way switch type, one-way switch type, and two-way open type. Due to the presence of fluid flowing out of the piping during separation, except for the two-way switch type. So please pay attention.
4. The usage environment of the quick connector (please select a quick connector with a suitable construction and material for the usage environment)
Consider selecting the type, material, and sealing material of the quick connector based on the humidity conditions, dust conditions, and easily corrosive usage environment.
5. Confirm that the selected quick connector thread should be consistent
In the process of using products from different brands, it is best to use the same brand's female and male heads together. If cross use is necessary, it is best to consult the technical personnel of the product supplier before use and confirm before use.
6. 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 piping characteristics. Please note that the size is related to the fluid flow rate.
