This adaptor allows a standard US low pressure regulator hose to be used with the Interspiro Divator MK II (AGA) Full Face Mask. In addition, the adaptor provides a 98 degree angle at the point it attaches to the MK II second stage. This is an important feature for Public Safety/Military divers who usually route their low pressure hose down to a manifold block.
This also decreases the chance for entanglement by placing the hose in close to the diver.
This adaptor is manufactured by “OmniSwivel International”. It is constructed from solid brass, and protected with an “Electroless Nickel Plating”.
