Heres another system: Hood w/ mask tied to a delay timing release

@devils~advocate and anyone else who knows stuff I've gotten myself terribly confused. Seeking guidance. I have my tank and regulator all set up and the hose barb fitting to connect to the vinyl tubing. That's a go.

I recently decided to use the allegro hood (9910-d). It came yesterday. I don't know how to connect it to my vinyl tubing. The specs say allegro uses rectus obac quick connect couplers (I believe typically this is connected to a breathing air hose which is attached to a compressor.)

My hose is 1/4 in, using the argon nut and nipple at the regulator. The hose is too small to fit on the end of the hood's low flow connector.

Ideas? Much appreciated!!! 2 photos, the first is regulator to hose using the argon nut and nipple. The second is the hose, the hood's hose and low flow quick connect coupler, and on the right is my spare argon nut/nipple and a hose clamp I didn't need so far.

No problems. The Allegro Hood barb connection appears to be a whats called a "High Flow" quick connect plug.

I can't determine the size without handling it personally. But find out what size it is.
What you need is a 'Coupler" that is made to accept this 'High Flow Plug'.
These high flow plugs/couplers are called 'V Style'. The webpage link describes in detail what these mean. Very interesting how they came up with these.
So when you search for them on amz, search for 'V Style'.

I think you need use something other than a vinyl hose from the regulator.
They make hoses that can connect to that regulator that in turn have a threaded end that allows a coupler to be attached to it.

The black hose in the image below is what I am talking about.
This particular hose has male connections on both ends.
One end goes connects to the regulator and the other end connects to a coupler.
The coupler shown below has a female connection end in order to connect to the hose.
I'd use sealant tape on all these connections. In the end, this would be an air tight configuration.

Then of course, the plug from the Hood hose would plug into the coupler.

When you get this system all together, please post a photo of it.
Its useful to see how all the parts look in a completed setup.
