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

Adapter: LP Reg Hose = BC Integrated 2nd Stage
Aqualung (Seaquest) Style Adapter: LP Reg Hose = BC Integrated 2nd Stage ScubaPro Style
  • Converts regulator hose to quick disconnect hose for BC integrated alternate air sources
  • Select from two (2) different type fittings that are specific to your brand (see options listed below)
  • 9/16-inch male end screws into an ordinary LP regulator hose - other end is a female slide-lock fitting
  • Adapter will add about {2 in | 5 cm} to the length of the regulator hose

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 types of this adapter, each is for a different high flow fitting. Each of the different quick disconnect female fittings works with one or the other of the male posts found on specific devices as follows:

  • ScubaPro Air II, Atomic SS1, Sherwood Gemini, Tusa Duo-Air IR3, Zeagle Octo-Z, and ODS (Private label sold by Blue Reef, Dive Rite, Hog and many others)
  • Aqualung AirSource 1&2&3 , Aeris Air Link, Apeks Octo Plus, Aquatec Air3, Oceanic Air XS 2, Sea-Quest and US Divers Air Mic.
  • Mares AirControl, XS Scuba MultiMax, and DGX Gears BCI
  • CEJN Beauchat Venturi and Zeagle Octo-Plus.

One of the fittings should work based on the cross reference above. Leaks are unlikely with our adapter and recently manufactured devices, but in rare cases might leak because of compatibility issues that are more likely with very old devices. SeaQuest (defunct - absorbed by Aqualung in 1990) and Oceanic brands (originally AUP , defunct - absorbed by Huish in 2017) seem particularly problematic as they apparently used several different suppliers for their fitting. If our adapter leaks you will have to resort to trial and error with different sources for what is essentially the same adapter design until you find a brand adapter that does not leak with your brand of device.

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 inflator but to avoid confusion we list that adapter separately.

Sometimes a few small pieces of gear can cost far too much. Not here. Great prices and prompt shipping. DHL shipping is fast but remember there will always be an additional 15. Buck min for handling charges internationally.

Quick-Disconnect Compatibility and Lack Thereof

​Three different QD posts

Divers are sometimes surprised to learn there is NO universal standard that defines the precise shape and exact dimensions of the quick-disconnect ( QD ) fittings used in SCUBA. This can cause compatibility issues with the connection: the fittings will not connect at all; the fittings will not securely connect and can self-disconnect without any overt user action; the fittings will securely connect but gas will not flow; the fittings will connect but will exhibit slow leaks. There is the further complication that the low-flow QD fitting commonly seen on power-inflators is not suitable for high-flow required by regulators, so QD fittings found on BC integrated second-stages use something else entirely.

  1. Low-flow BC power-inflator Schrader valve QD common to all BC brands sold in North America
  2. High-flow BC integrated 2nd stage QD common to ScubaPro Air II, Atomic SS1, Sherwood Gemini, Tusa Duo-Air IR3, Zeagle Octo-Z, and ODS (Private label sold by Blue Reef, Dive Rite, Hog and many others)
  3. High-flow BC integrated 2nd stage QD common to Aqualung AirSource, Aeris Air Link, Apeks Octo Plus, Aquatec Air3, Oceanic Air XS 2, and US Divers Air Mic

The low-flow QD posts can be further divided into two styles: a more widely seen post with a shorter barrel and a raised bridge across the top, or a much less common post with a slightly longer barrel and a flat top. In our experience, the flat top post seems more likely to be encountered in the UK and to a lesser extent in Europe; it's almost never seen in North America or Asia. Hoses designed to fit one style of low-flow QD post are less likely to be compatible with the other. However, even within the bridge top post design we have encountered occasional incompatibilities, usually when there is many years difference in age between the male and female fittings.

First the good news... low-flow QD fitting incompatibilities are rare. All the low-pressure quick-disconnect inflation hoses we sell are compatible with the post found on our replacement power inflator as well as the inflators on all the wings we sell. If you are concerned about compatibility, the best strategy might be to replace the power inflator and hose simultaneously from the same source. Keep in mind that if your BC hose and power-inflator are more than five years old, best practice is to replace them anyway.

Now the bad news... high-flow QD fitting compatibility problems are commonplace. You can not use a standard inflation hose to supply a BC integrated alternate air source, as the device would not receive enough gas due to the restriction of a low-flow fitting. There are several different types of the high-flow fitting commonly seen on BC integrated second stages. If you are concerned about compatibility, the best strategy might be to replace the QD hose with the same brand from the same source as the original equipment manufacturer.

We recommend using the OEM hose for your brand of BC integrated 2nd stage, but if you can't find an OEM hose then we do stock high-flow QD adapters that allow any standard-length LP regulator hose to be converted into a quick disconnect hose for BC integrated alternate air sources. The adapter 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. Each of the different quick disconnect adapters works with one or the other of the male posts found on specific brands. A snug fit is a desirable characteristic in all quick disconnect fittings; it means the fitting is less likely to "self disconnect" or the o-ring seal to leak. However, it also means you must take care to hold the locking ring fully retracted while forcefully and completely pushing the fitting on to the post, then pull back on the connected hose to ensure secure connection. Unfortunately, in some cases the adapter might leak because of compatibility issues that are more likely with very old and/or worn posts. It the case of the SeaQuest brand Air Source, it's probably time to retire that device, you should also seriously consider retiring the entire SeaQuest BC; they are both over 30 years old.
