Cutting rubber AC lines

[garys 68]

I need to make some custom length flexible rubber AC lines and take them to a shop to get the ends crimped on. What's the best way to cut them?
I've got a cable cutter, but it does crush the hose a little. I hate using a cutoff wheel because of the debris it can throw inside the hose.
What's the best method?

You can use cut off wheels for high pressure hose. Just cut the exterior of the hose all the way around without going through. Kind of a deep scoring around the hose. Then make the final cut through the remaining bit. This will limit how much debris is passed into the hose.

But, I would probably just measure what you need, then have the shop that is going to be putting the crimps on cut the hose to length. Most places will have chop saws with the correct style blade. They are usually very slow cutting blades and do not melt, or throw any debris around.

Also, any debris that my get into the hose can always be cleaned out.

I used a band saw to cut our hoses and just blew the debris out before taking them to Napa to be crimped.

I used a saw as well, worked fine.

I use Earl's Tubing cutter. Use it to cut A/C hoses up to size 12, for heater hoses, for the new style flexible braided (non stainless) lines. Best $40 I've spent in the plumbing dept. Nowif I can just find replacement blades. Been using same blade for 2 years over 200 cuts and still going.

We use that Earl's cutter also, it's slick.

Thanks on the Earls cutter, looks good.
I need the length and orientation of that angled fittings correct. So with 4 hoses, I think it's best I cut the length and mark the fitting orientation.

On my last car, I just used heater hose and created 'templates' for the AC shop to use. The heater hose is much easier to work with as you are experimenting with bends and placement, then I marked the hose to position the orientation the way I wanted. The shop did the cutting and aligned the fittings as I requested.
