Where can I get water injection fittings?

I am looking for the spray bar for water injection (the one that sprays a fan in one direction).

How much? (PM me if you want)

Also, does anybody know if I can get one from Mcmaster? I have been looking through their parts but haven't found one yet.

I also found these...

I'm going to bump this back up. I found the one on blowsion but it says it is a 1/8" (hose) fitting, the one I had in my last pipe was a 1/4" fitting. Where can I find the 1/4" one?
