Description: Feature:Nickel plated or chrome plated, corrosion and rust resistant. Self-locking design, more convenient to use. Reduces accidental airline disconnection. Pneumatic quick coupling is a kind of quick coupling mainly used for air pipelines and pneumatic tools. It can connect or disconnect pipes without tools. Spring-loaded quick couplers that should be used on the compressor so that air is contained when the air tool is disconnected. When using the coupler(s), slide the sleeve back, push the connector in, and then slide the sleeve back all the way to lock the connector. Scope of application: pneumatic pipe, air compressor, grinder, air drill, impact wrench, pneumatic screwdriver and other quick connectors to connect pneumatic tools. Specifications:Item Type: Quick Connector Material: Metal Size: SH Total Length: 66.8MM/2.6in, PH Total Length: 52.8MM/2.07in Color: SilverOptional Type: 2020, 3030, 4040Quantity: 1 Pair Warm Tips:1. When designing the hose path, the spatial position of the pipeline assembly and disassembly and debugging should be guaranteed to avoid interference to the mechanical device on the pipeline.2. Before taking over, use compressed air to blow out the debris in the hose and connectors.3. The wiring should be neat and beautiful, grouped and numbered, and included for easy inspection. Attention should be paid to the operating environment temperature of the hose, which directly affects the pressure resistance and reliability of the hose operation.4. The hose should not exceed the required length to reduce the air pressure loss in the pipeline. The radius of curvature of the pipeline exceeds a certain value, and the bent part should not be too close to the joint to avoid leakage and prevent the hose from twisting.5. When tightening threaded pipe, pay attention to the appropriate tightening torque. The table below shows the permissible tightening torque. Note: No retail package.
