The old AquaLungs do not have LP (or HP) ports. So, you can't add an octopus or an inflator. The AquaMasters (DA and Royal) do have a hookah port, however. The hookah fitting allowed the regulator to be hooked up to a surface-supply air hose. The threads on this port are the same as for an oxygen regulator. I visited an industrial hose shop and explained that I wanted to reduce the hookah fitting to a LP port. The attached picture shows the result. The chrome nut is the original hookah port cover. The adapter has DIN style captured o-rings on both ends. I was going to screw a three-port swivel adapter into this (for separate inflator and octopus hoses), but the assemble was so long that it looked like it would break if it were hit against somthing. So, I instead screwed in a single hose inflator integrated octopus (like a Sherwood Shadow) and routed the hose under the regulator to the left. I replace the original short hose with a longer octopus hose to make up for the hose length lost in the curved routing. The rig looks good and works. I hear no air leaks and can now dive my old double hose with an inflator and octopus. A Dacor valve with HP port will allow me to add a pressure gauge and my AquaLung will then be provided with all the modern conveniences.
