I am installing an AC condenser which has o-ring connections. The tube hardline needs a simple formed ring/step about 3/8" back from the end. I am lost trying to find the right tool to form it. Can anyone help?

Also who's a Fabricator expect should hook me up with some training. I'll be willing to pay for the time

 

I can't help you as far as forming a blank hard line but, you can buy straight sections of A/C hard line in varying lengths. You just have to bend them the way you want. That's what I used to build a system for an antique truck I have.
