Low Pressure (LP) 9/16 inch Male UNF to ScubaPro and Tusa scuba inflation and octopus coupling adaptor.
This Low Pressure (LP) 9/16 inch Male UNF to a ScubaPro Air 2 and Tusa Duo Air type Ocy Inflator coupling adaptor lets you convert any regulator hose a BC quick disconnect inflator hose for certain combined BCD inflator and octopus couplings.
Some BCDs come with a BCD inflator unit that is combined with an alternative air source (Octopus) second stage regulator. The manufacturers of such units often use a proprietary coupling so that their special regulator hose can provide the extra air flow that an Octopus requires over a standard inflator hose and still have the quick disconnect features of a standard inflator hose.
This adaptor lets you use a standard inflator hose to connect to the special quick disconnect fittings on the ScubaPro Air 2 and Tusa Duo Air and compatible BCDs.
