I'm not good at explaining.

Your explanation is fine. Let me look up some part numbers.
Meanwhile, you can add a B fitting end to your long hose so you can attach the Y adapter. You will need a hose to connect from the Y adapter to the Y splitter for your Scorpion. I don't know the configuration of your Little Smith torch, I believe that torch is pre-mix, so if you don't have flashback arrestors/firechecks on your Scorpion, you surely will need them for the Little Smith.
(I realize you are probably using oxygen concentrator(s), but I am including oxygen part numbers for completeness.)
OK, off to find part numbers.
Also, look here for less expensive Y connectors:

Edit to add part numbers --
First, for your long hoses:
if you have 1/4" hose, use parts 40-B (oxygen) and 41-B (gas)
id you have 3/16" hose, use parts 40 (oxygen) and 41 (gas)
These have a barb on one end and a male B fitting on the other.
40:

41: (Need to find a vendor)
40-B:

41-B:

To go from the Y adapter to your Scorpion Y splitter, you can use these:
Flashback arrestor hose adapter:

or
Pigtail adaptor to fit barbed torch ends:

In my opinion, you should get rid of those automotive hose clamps and get some Western Enterprises hose clamps (also you will need some for the barb to B fittings):

or, if you can find them, you can get the 312-501 size, but those are out of stock at this particular vendor.

So, I've been thinking about my statement about flashback arrestors. Perhaps any flashback damage would be relatively minimal. With an oxygen concentrator, there is no storage and limited output capacity, and I doubt whether people use check valves or flashback arrestors with oxygen concentrators due to the pressure loss. While the oxygen concentrator probably won't push the combustible mixture back through the propane hose, it is probably safest to use one on the fuel hose.
