Hi All,
I've been using silicone rubber tubing as my laser-cutter coolant piping for almost 3 years with no problems... until last night.
I was running a job and heard a popping noise. I looked over, and I've got coolant squirting against the wall.
The tubing had deteriorated where it attached to the pump.
I've got an EFR ZX-1250 glass-tube laser and use food-grade (motor-home type) antifreeze as the coolant.
What's the best tubing/attachment to use?
Thanks for any advice!
Tim
