Hi guys, I am in the process of replacing my air compressor pressure switch and the nut that connects the copper tube from the compressor to the switch is a different size on the new switch than on the old. How do I remove the old crimp thingy so that I can get the old nut off? I am thinking using a die grinder with a small cut off wheel.
some times you can work them back and forth with a pair of pliers pulling at the same time options take a hack saw blade carefully cuting brass bushing --Do not nick the copper line!!!! untill almost thru then you can get bushing to crack with pliers or buy a short piece of line and start over or you can buy adapter bushings from old size to new
Looks like a compression fitting. They are a one time crimp. If there is enough tube you can simply cut it off and install the new nut and ferrel. Once you tighten it it will self crimp. If it's not going to reach you can cut it off further down and ad a section on with a compression union, ..... then install the new nut and ferrel. Larry
Thanks guys. I used a hack saw and cut the tube just below the fitting. My compressor is back in action!
