new product from DR

Check it out. A fitting has been designed to screw directly onto a 2nd stage which can allow a inflator hose to be connected to it. You can now access your onboard oxygen very simply. This is very nice if you have large on-board oxygen cylinders. Part number is DRT-43-1 and MSRP is $29 U.S. They're brand-new so be patient if your DR dealer doesn't have it in stock yet.

Hmmmm

I'll have to order some of these and try one out

Yes those things have been around. Can be bought as an add on to the Ocean Reef FFM. But with a CEJN-connector.

I just happened to order machining of a couple of this sort of adaptors for my sling-Rebreather ADV and for add on 2'-stages.

But I'm cuirous, does a std BCD type connector have enough flow for breathing? I guess DR figured it has?

I remember discussions about it and that a CEJN-fitting is better because of its better maxflow. And all those Air2, AutoAir and similar devices. They all use other connectors than std BCD. Must be for a reason?

At 20 feet and up, it does. It is not nearly as much flow as you are used to, but it is enough. You need to consciously breathe a little slower and longer, but it works just fine. Another thing, I wouldn't call this a std BCD type connector, as the holes on the end are bigger.

To be breathed at greater depths than 20 feet

OK

And then there is also this thing:
Air Buddy for a BCD

I bought one a year ago and it acually works. I only used it on a few occasions to test it. Downside is it has to be more or less premanently added to the hose.

I bought a few of these from another source a while back, though they had bigger diameter holes. Unfortunately, unlike the APD GCS, I found that they did not have a one way/ non- return valve. This means that though you have a dinky little reg stuffed into a pocket with one of these fittings on, water will get behind the valve.

Hi Jordon, it looks very much like a BCD connector and at 10m or less the flow should be sufficient,
but with any intent of using at depth, I would use caution.
In an overwork situation or a stressed situation such as C02 hit, it may not deliver enough air.
In my case where I use a DSV/BOV I use large flow quick disconnects
on the BOV and on all my B/O bottles.
Take care,

Cornel

I’d view these as for EMERGENCY extension of deco use only.

Several years ago I was merrily machining my own manifolds for QD connection of both bailout 2nd stage and wing inflation from off board 1st stage. Originally used a standard BC inflator hose to a BC QD male connector on manifold. Wings worked fine but 2nd stage was like breathing thru a soda straw. If a diver was going OC as a bailout in anger, IMHO any BC type connector would not provide sufficient flow. If one were in a relaxed situation, say trying to access a little extra O2 to extend deco, perhaps but even then highly marginal. I went to one of the bigger bore connectors mentioned and all worked well.

There are 2 major restrictions to the flow. The one you see at the end of the male connector is one. The other is a Schrader valve hidden inside the connector end of the BC hose that is dimensionally identical to the one in your tires on your car/ bike/ whatever. Look at one of those up close & personal and you’ll see why the flow is so low.

Just my $0.02.

Yes, water will get on the other side of the inlet tube, so extra care (flushing with fresh water) needs to be taken if you use one of these in salt water.

These work well at 20' and up, as I have tested them. They are inexpensive so get one and try it out. A 2nd stage easily fits in a drysuit pkt. I would hate having to bailout and need extra O2 to deco with and not be able to access the onboard supply. Moreover, if I am doing a relatively short dive and I am starting out with a full, onboard O2 tank this is all I bring for deco bailout. Very nice eliminating a tank. If I am doing a long or deep dive, I still bring the offboard deco bailout.
