Any basic bleed kit will have the bits you need.

That barb piece 'might' work (it's actually the one for the lever), but the one you really want has a threaded section only about half as long and has a flange near the nut flats. You can see it on this video at 1:34

The ebay bleed kit is all you need for bleeding. I have one too and it contains the threaded fitting that attaches into the brake port.

The barb from eurocycles is only needed if you have otherwise damaged the hydraulic hose attachment at the lever. Not at all needed for standard bleeding.

Great thanks everyone!!
