If there is room/space you could apply 3 Clamps per Hose end.

The advantage is that the Real Crimp Tool for the Oetiker Clamps is around $30 with copies or other makers tools for less or cost more depending on the features you need.

Or you can use a Nail Cutter or Tile Nippper at $5 or less as I did on the Oil Cooler ends of My Oil Cooler Hose to apply the Oetiker Clamps..

It is the same type of tool used for PEX tubing, which I have the tool. I think 2 clamps per fitting would work fine for the DIYer.

I used the Shark PEX Clamps (functionaly the same as Oetiker) Clamps to make up a set of Flexiable Hoses for My Mom's Water Heater.
I was going to use PEX but I found out it cannot be right next to the Hot Water Oulet on the Water Heater.

Aeroquip EZClip System

One of my neighbors was asking me how to delete the AC system from his late 1960's GM sedan and it had those style claps on the AC lines. I was confused when I saw them because they were not the crimped-on style that I am used to. Until I saw this, I thought someone used PEX clamps to home-make the AC hoses.

When I was searching for a crimper to make A/C hoses, I saw an entire line of this style clamps used for A/C hoses. I am sure someone is using them, as many different sizes were available specifically designed for A/C hose applications. I opted for the traditional system because of the good selection of bead-lock fittings available. The clinch type clamps require barbed fittings and no sleeves. I am using all steel fittings, and very few plain barbed steel fittings are available. Plenty of aluminum, but I will not use aluminum fittings on a Diesel A/C system.

Are the blue liquid lines from the factory? I'd like to rebuild them as well with my A/C project, but the evaporator fitting is not a standard fitting? Can I cut off the crimp collar and have a shop crimp on a new ferrule? I assume there's a barb fitting under there, but I'm not sure... anyone know?

Yes, those lines are factory lines. HoseFast did not have to weld anything to the liquid lines I brought to them, so they should be standard AC sized lines. The fittings should have barbs on them.

As far as I know they are metric, and my local hose guy did not have anything but SAE. I have done the low side hose going into the cab by welding on a #12 barb to the factory fitting. The high side hose going into the cabin (blue) is made of some different kind of material that does not wear out like the larger rubber hoses, and in my opinion does not need to be replaced unless damaged in some way.

The outside of the hose is a vinyl or similar material. The inside of the hose looked like rubber to me. You are right that it is very rare to have to replace this line. Animals had eaten through some of the hose on mine and I did not feel comfortable (over the long run) charging the system with that valuable R12 with damaged hoses.

Metric or SAE, HoseFast had whatever it took to do the job without welding.
