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
Features to Look For:
-
Automatic shutoff valve (prevents air blowback)
-
One-hand operation
-
High flow design (for impact wrenches and air drills)
-
Swivel couplings (prevent hose kinks)
Applications:
-
Air compressors
-
Pneumatic tools (drills, nailers, grinders)
-
Robotics and automation
-
Spray painting
-
Automotive repair
