A pneumatic coupling (also known as a pneumatic quick-connect coupling) is a mechanical fitting used to quickly and easily connect or disconnect air hoses and tools in compressed air systems.
These are essential in applications like:
Workshop air tools
Industrial automation
Pneumatic control systems
Automotive garages
Paint spraying
Automatic shutoff valve (prevents air blowback)
One-hand operation
High flow design (for impact wrenches and air drills)
Swivel couplings (prevent hose kinks)
Air compressors
Pneumatic tools (drills, nailers, grinders)
Robotics and automation
Spray painting
Automotive repair
