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.

Dry Aviation Couplings - Selectivity
Selective units are fitted with setting rings. These have slots cut into them to match up with the corresponding pins on the selective sleeve on the hose unit. Care must be taken when reassembling such units to ensure that the ring is returned to its original position.
