Schrader Heavy Duty Couplings (manufactured by Parker Pneumatics) are generally suitable for most fixed compressed air applications.
Schrader Heavy Duty Couplings are designed for single hand connection or disconnection. A twist on the cap will release the adaptor and the airline is automatically released. When coupled the coupling allows the adaptors to swivel, to eliminate kinking of the hose.
