DGX Adapter: LP Reg Hose = BC Integrated 2nd Stage

You can not use a standard BC inflator QD hose Schrader fitting to supply a BC integrated alternate air source, as the device would not receive enough gas due to the flow restriction of a standard Schrader fitting. These adapters allow any standard-length LP regulator hose to be converted into a quick disconnect hose for BC integrated alternate air sources. The 9/16-inch male end screws into the second stage end of an ordinary LP regulator hose, and the other end of the adapter is a female slide-lock fitting that accepts the hi-flow male post found on BC integrated second stages. The adapter itself will add about {2 in | 5 cm} to the length of the regulator hose. Important: There are different adapters, each is for a different high flow fitting. One of the adapters should work based on the cross reference below and leaks are unlikely with currently manufactured devices. Each of the different quick disconnect female fittings works with the male post found on specific devices as follows:

• ScubaPro Air II, Atomic SS1, Sherwood Gemini, Tusa Duo-Air II, Zeagle Octo-Z, and ODS (branded as Blue Reef, Dive Rite, Hog and many others)
• SeaQuest style† See Note Below Regarding CEJN Compatibility
• Mares Air Control, Aqualung AirSource 3, Aquatec Air-3 & Air-300, DGX Gears BCI, Oceanic Air XS 2, and XS Scuba MultiMax

† Various copies of the proprietary CEJN original 5mm high-flow couplings were used on some devices which are no longer manufactured such as the Aeris Air Link, Apeks Octo Plus, Beauchat Venturi, Oceanic Air Link, Oceanic Air XS, SeaQuest/Aqualung Air Source (but not the current Aqualung Air Source 3 model), US Divers Air Mic, and Zeagle Octo Plus. Collectively the quick-disconnect fitting on these devices is often generically referred to as the SeaQuest style connector (or sometimes Aqualung who later absorbed the SeaQuest brand), although there are slight variations among the devices. While the generic SeaQuest style posts look very similar to each other, in our experience the adapter may not be reliably compatible with every one of the posts on these various older devices. The Mares style adapter may (or may not) work better with a SeaQuest style post on your specific device, but if not then perhaps the most expedient solution is to consider replacing your obsolete device with a DGX Gears BCI Backup Regulator.

The low-pressure regulator hose is NOT included with these adapters. The adapter itself will add about {2 in | 5 cm} to the length of the regulator hose. The suggested lengths of the LP hose regulator hose are:

• 24-inch LP Reg hose is suggested for typical sport BCD length 19-inch corrugated hose
• 22-inch LP Reg hose is suggested for typical technical aircell length 16-inch corrugated hose

While it does not work to adapt a BC inflator hose to a regulator, it is possible to adapt a LP regulator hose to a standard BC QD inflator post but to avoid confusion we list that adapter separately (see related products above.) Having the additional low-flow BC inflator hose adapter in your save-a-dive kit provides an easy way to use your regulator with a different BC that has a common low-flow BC QD post simply by swapping the adapter on the end of the hose.
