Inflator hose doesn't fit on inflator.

[Couv]

Please allow my lazy cut and paste from a thread about 10 years old:

IMO the best method of connecting an inflator or inflator/regulator to your first stage is with a standard second stage (or Miflex) hose coupled with a screw on adapter with a quick disconnect. There are a few advantages to doing it this way. For one, l/p second stage hoses come in a large variety of lengths making routing much simpler. Additionally, should the hose become defective one only needs to change it out and reuse the adapter. See the picture below for examples of 3 male ends the quick disconnects attach to.

There are at least three sizes that most inflators or inflator/regulator fall into:

1) The "standard" <--- most inflators

2) Tusa DuoAir, ScubaPro Air 2, Atomic SS1.

3) Oceanic Air XS, Aeris Air Link, SeaQuest Air Source, Apeks Octo Plus, Zeagle Octo Plus, US Divers Air Mic.

Thanks for your help.

Since I was present at a very bad accident, that first began as a diver and an operator discovering half way to a dive site, an issue fitting the rental regs that the diver requested, to the Air2 set up that the diver was using, I try to be aware whenever diving with someone using one.

My brother himself dives an Air2, and since my experience he has added a double set of adaptors on his rig. The adaptors will fit an Air2 rig to a regular reg, or the opposite, but plugged together they have no impact on his rig, other than giving him the ability to solve potential issues down the road.

Am I getting this right, he converts from a normal, small diameter, inflation hose to the larger connector on the Air2?

So no I pact than flowing less gas than the design calls for?

The Schrader valve cannot flow enough air to supply a regulator, but can be an inflator....

I'm sorry I took so long to respond, but I wanted to speak with my brother first.

Yes, my brother now carries 2 adaptors which if used together would restrict the flow to an air integrated inflator, if they are used. They travel at all times with his rig though, just in case.
One adapts up, and the other, down, so he can quickly add a standard regulator system to his bcd, or use a rental BCD if his ever turns belly up, or disappears.

We are not talking optimal here, or even peak performance, if an adaptor should be used on a dive, but adapting to equipment difficulties in less than ideal situations, often in rather remote locations is a part of dive travel most of us have seen or had to deal with.

I believe that in an emergency, just having the ability to breath anything at all at depth, and then being able auto inflate the bcd once the diver is on the surface, was seen as desirable, even if the alternate regulator does not breath at peak performance at depth.

Note that this is part of a save the dive kit, and not for daily use. I have noted elsewhere that in the case I saw, the diver was traveling with personal gear, that included the Air2, but for a reason I was not privileged to know, a rental regulator was requested by that diver from a local operator, and no one ever mentioned connectivity, or Air2, until we were all nearly on the dive site.

At the point where something like the restriction of an adaptor might become an issue during a dive, you are not going to continue the dive as if everything is peachy, anyway, so peak performance takes a back seat to survival.

I have read many post here that expressed a concept similar to: "I'd breath a fart out of a monkey's ass, if that's what it takes to reach the surface". You do not inflate a bcd until you reach the surface, where there is air you can breathe, so even marginal performance is better than no gas.

I do know that adding the 2 adaptors to his kit as my brother has, will allow him some ability to resolve an equipment issue, besides orally inflating, and having no alternate at all when diving in a remote situation, which is exactly what I witnessed.

In that accident, the diver apparently was uncomfortable with the idea of orally inflating, and, or may not have had enough practice at this. There were other contributing issues that probably led to the fatality, but everything seemed to cascade from that mismatch of equipment before the dive even started.

I do not have all of the details of the accident, as I was escorted away before any investigation began, so I have just my observations at the time, and the little bit that I learned later.

I assume then that he has a proper large bore hose and an air2 normally and all is as specified by the manufacturer.

Then his problem will be if he loses use of his regs with the correct hose? In that case I suppose he has a proper octopus and would not need breathing rates of flow for the air2.

I have recently been playing games with quick disconnects for a CCR bail out valve and not restricting flow is a key consideration.

I'm the brother in question. Yes, your description of the lost/failed regulator is correct so not the concern expressed in this thread. The opposite scenario is lost/failed BCD in which case I have and could use the A2->standard adaptor to connect my regulator to rental BCD (but note this scenario leaves me without safe second so "not ideal").

There are a host of other scenarios as well: like A2 inflator hose failure at a remote resort where the only replacement hose is standard. This scenario is the one where the gas delivery rate to A2 regulator is the subject of concern in this thread. As stated earlier in the thread I have experimented with this set up and am convinced I can breath sufficiently through the scrader valve in the QD of the standard inflator hose (keep in mind it is me breathing on the A2).

Ended up just buying a new inflator hose with the correct end.
Thanks for all the info,
