I lucked into an aftermarket HVAC system for my 1980 CJ7. Al fo the hoses needed to be assembled/swedged. I looked at all of the available options, and settled on this one, for a number of reasons. I was working on a budget, would probably only need the tool this once. Using a hydraulic or pneumatic version probably would have been faster. These systems are no joke. Solid steel, weighing a ton, and providing excellent swedges. Being a manually operated device, it takes a minute to open or close. If you're on a budget and need something that will be reliable, good quality, and provide good service, there are worse options out there.
