ABSTRACT:
A pressure balanced coupling device for quick connection and disconnection with at least one mechanism. The device operates to maintain a sealed flow-through connection between two devices which may also contain a pressurized medium such as refrigerants. The preferred device permits non-destructive gripping of tubing while affording readily selectable means for safely releasing pressure from within the device prior to releasing the gripping connection provided by this coupling device.
