My compressor has a female coupling that, I assume, connects to 1/4inch Industrial type connectors. Using my calipers I measure the interior diameter to be 0.27 inches. This is the type shown in red in the photo.
The solder paste dispenser comes with a large connector with a different shaped barb. In the comments on yesterday's video someone suggested it was a 3/8th inch coupler. After a little research though, I think it is the 1/4 or 1/2 inch "Asian Style High-Flow" shown in the picture. The barb shape matches exactly. The ID is .28 or .29 inches, so I'm going to guess it is also the 1/4 inch type.
Any thoughts or ideas?
Here is the PDF reference I used:

Update: Found this, seems to be the right one. Now how to do a proper adapter...
