I don't know.
I had no problems with kinking, and I think the stuff I used was thick
They make springs you slip over the tubing to bend it without kinking, but I
did not need it.
The more copper, the less resistance, so try the thick stuff.

I am going to wind a pi section tank coil from 1/4" copper tubing
tomorrow. Mine will be 4" in diameter and 3" in diameter. Which tubing is
best (no kink) thick or thin? Thanks.
