it's a lot larger than 8 mm. the zero tip is the red one in this pic, and the stainless steel part is probably about the same diameter as your pinkie finger, and the adapter it snaps into is a lot larger.

However, the hole in it is probably 1 mm or so.

So scratch that. I'm not sure if there's anything magical about it anyway; it might be simply a hole, and you can experiment with drill sizes to optimize the end of your barrel. I'm assuming the opening will be a lot less than 8 mm, which I believe is way to huge to shoot a jet of water 5 m, unless you have super high pressure.
