The above is an ASME spec for nozzles. There's a 10 degree taper on the inside lip, and I believe that it may be for air, but I could be wrong. Either way, it should work fine.

I doubt the 10 degree taper will hurt anything either.

What pump you got? The nozzle in mine right now is 1/8. As for the flow, I couldn't tell you what it is now but I suspect it's been cut in half atleast. It's working though much to my amazement. But you have the fins in the center to so thats different, I forgot again.:shrug:

Kind of like mine now with the first one but more flat on the inside. Adding more flow through it and pressure it will start to get a pattern spray to it much like a garden hose. Not bad though with the hydor pump. Second is the way to go.

Thanks for sharing and pointing me to the ASME specs! I'm really interested in the nozzle you found. You'll be amazed when you try it out. I have a feeling your radius will knock the socks of them with impingement. Block I'm using now has NO fins/channels. I was shocked to see the results with just my crude version of jet impingement though mine is off center of the die! I didn't realize the cpu die was offset.
