Question about air nozzle fittings

I'm taking automotive classes in college and I have a tool list that I have to complete before school and there is a thing on the list I can't find...

Air Blow Nozzle with Air Fittings Type "C" required

Does anyone know where I might find this or even what the type "c" fitting looks like?

Thanks

 

I did some searching around and this is what I found.
This is just an example. You would, of course, have to buy one with the right thread size.

Wow....you have to do what...for college?

So, they gave you a list of tools and you have to find out what they are?

What type of application does this AIR BLOW NOZZLE used in? Is it an air gun?

If you go to McMaster CARR website http://www.mcmaster.com/#
Type in: Type C air fittings
You'll get:

Then type in Air blow nozzle
You'll get this:

McMaster Carr rules for this type of stuff. Everything and anything you need.

 

Thanks for the replies guys. No, they give me a list of tools and I have to go buy them. lol

 

Thanks man. That looks like what I need.
