What tool do you recommend for crimping refrigeration lines when changing out a pressure switch or hot gas valve on a Manitowoc Ice machine?
A pinch-off tool that's like a vice grip, but have very narrow jaws. They look like the left one in the link:
I don't recommend using regular vice-grips.That'd never work.
You'll need to re-round the tubing afterwards so refrigerant pressure can flow through the section you pinched off. I just use my flaring/swaging bar. In the link, they show another version of a pinch-off tool that's also includes the re-rounding holes. I've never used that version and is probably pricier. If you have a flaring kit, then that would suffice as a re-rounder tool.
The one on the right works great!
Looks like it would. I know that when I used the vice grip version, it was always a judgement call on getting it adjusted just right, since it gave me the impression that it could cut through tubing like dikes do to wire.
