This is what I am talking about: https://www.autoacfittings.com/Weld-On-Beadlock-Ends-Aluminum-Standard-BL-6601.htm I ordered some with new hose. I have a crimper that got second hand. Can't remember the make/model off hand but can check if anyone wants to know. It is USA made and was only about 80 bucks lightly used.
