One of our Members used an A/C crimping Tool to make His Oil Cooler Hoses and even used the A/C Hose on it. For some reason I did not save the Threads to My notes:
I am guessing if someone picked one of the words like Mastercool and searched they could find the thread.

"Galaxy® 4890 SLE A/C Refrigerant Hose A/C hose (used #12 Hose= 5/8“)
Mastercool 71550 Manual Basic AC Hose Crimper kit MA71550 $146"

I guess I am even a bigger Thrill Seeker.
When I first tried to replace My Oil Cooler Hoses with only Hose and Clamps I had to take one old Hose apart to get the size.
I ordered 1/2" Hose that ended up being too tight to fit.

The Mercedes was the only Car I had to get to work in and one Hose was taken apart.
It would be as long as 2 weeks till the 5/8" ID Hose I ordered would arrive.

I bought some extremely heavy Duty 5/8 ID Heater Hose and used that with Hose Clamps till the correct Hose came.
I only drove to places I absolutely needed to go to and tried to keep an Eye on the Oil Pressure Gauge till I got the Right Hose.
I also stayed off of the Freeway.
I had no issues with the Heater Hose use for that short time. But, not recommended
