Genuine Schrader couplings (manufactured by Parker Pneumatics) and adaptors are generally suitable for most fixed compressed air applications. 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.
