How Dry Aviation Coupling Works

The Dry Aviation Couplings include a bayonet-type connector and are flanged or threaded to suit installation requirements. Each tank unit contains a “fail safe” springloaded valve seating on a tapered seat. The valve is controlled by the action of coupling and uncoupling the hose unit.
