Features of Stainless Steel Quick Coupling:
1. Time-saving and labor-saving: When the oil circuit is disconnected and connected through the quick connector, the action is simple, saving time and manpower.
2. Fuel saving: When the oil circuit is broken, the single valve on the quick connector can close the oil circuit so that the oil will not flow out and avoid the oil pressure loss.
3. Environmental protection: When the quick connector is broken and connected, the oil will not spill and protect the environment.
4. The equipment is unique in design and easy to transport: large equipment or hydraulic tools that need to be easily carried can be transported after being disassembled using quick connectors, and then assembled and used after reaching the destination.
5. Economy: All the above advantages have created economic value for customers.
Precautions for the use of stainless steel quick joints:
1. Please do not use it for fluids other than applicable fluids.
2. Do not exceed the maximum operating pressure limit during use.
3. Do not use outside the temperature range to prevent wear or leakage of the sealing material.
4. Do not hit, bend or stretch artificially to prevent damage.
5. Do not use in places mixed with metal powder or sand to prevent poor work or leakage.
6. For threaded installation, do not exceed the maximum tightening torque during installation to prevent damage.
7. Do not use hoses with cracks to prevent leakage or falling off.
8. If it is used in a machine with vibration or impact, the durability will be reduced.
9. The fluid used must be clean fluid filtered by a filter.
10. Do not disassemble the quick connector.
