Supplied by OmniSwivel International, this adapter offers a fixed right angle to connect a standard low pressure regulator hose having a standard 9/16-inch fitting to the special M16x1 fitting found on the Interspiro brand Divator (a.k.a the 'AGA') Breathing Valve found on their line of full face masks.

The OmniSwivel AGA swivels fit AGA masks made after 2005 directly without the need of any modifications. Older masks need to have the gray plastic 13 mm retention nut that holds the valve onto the mask replaced with the updated 19 mm version.
