It reduces the time required to replace air tools and service compressed-air connections. **Self-Locking Coupling Structure** The coupling and matching plug are designed to stay securely connected during normal operation while allowing the operator to disconnect the line when required. **Male and Female Connection Options** Different socket and plug configurations are available to accommodate air compressor outlets, pneumatic tools, air hoses, valves and industrial air lines. **Multiple Thread Standards** PT, BSP, NPT and metric thread options can be supplied according to the installation requirements of different pneumatic systems. **Compatible with Multiple Tubes** The product is suitable for PU, PA, PE and PVC pneumatic tubing when the correct tube size and connection configuration are selected. **Suitable for Air, Water and Vacuum** The current technical data lists air, water and vacuum as applicable media. Actual suitability should be checked according to pressure, temperature and medium compatibility. **Easy Manual Operation** The release mechanism allows the connection to be operated by hand without special tools. This is useful for pneumatic tools that need to be changed frequently. **Adjustable Installation Direction** After installation, the hose direction can be adjusted according to the fitting configuration and available installation space. ### Applications **Pneumatic Tools** Used with impact wrenches, pneumatic screwdrivers, air drills, grinders, blow guns and other compressed-air tools. **Air Compressor Connections** Suitable for connecting compressor outlets, air hoses, quick couplers and workshop air distribution systems. **Workshop Air Lines** Used at maintenance stations and industrial workbenches where pneumatic tools need to be connected and disconnected frequently. **Factory Automation** Suitable for pneumatic equipment, automated machinery, cylinders, valves and production-line air connections. **Air Blow Gun Systems** Can be used between air hoses and blow guns for quick tool replacement and convenient workstation operation. **Maintenance Equipment** Useful for repair shops and service stations where different pneumatic tools need to share one compressed-air supply. **Industrial Water and Vacuum Lines** The product data also lists water and vacuum as applicable media. The actual fitting, seal and pressure rating should be confirmed for each application. ### Why Choose HOMIPNEU HOMIPNEU supplies C Type quick couplings, pneumatic fittings, air hoses, quick connectors, solenoid valves, cylinders and compressed-air accessories.
