Keggle to counterflow chiller question

[Blindguardian]

I finally have gotten my new burner KAB6. I have finally gotten my counter-flow chiller made and keggle set up.
I have set my keggle up with a weld-less bulk head and valve from bargainfitting.com
Now I have a question.

How do I hook up the 1/2" NPT barb nipple from the keggle to the counter-flow chiller that has a 3/8" end? I know you have to use a 1/2" ID tube off the nipple but will the tube tighten down enough to make a good seal on the 3/8" end of the counter-flow chiller?

Let me mind you I will be gravity feeding the chiller.

Any close up pics would help me out greatly.

thanks

Go to your local hardware store and buy a hose barb adapter from 3/8" to 1/2".

They should be available in both brass and plastic. Take your pick.
