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
