Product Features
Quick Connect and Disconnect
The C Type quick coupling is designed for fast connection and disconnection of pneumatic hoses and tools. 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.
