Sealer when recovered into an unsuspecting a/c shops machine will really mess up the machine, sticking solenoids and other nasty things. I really hate to see it used.

There is so much junk refrigerant in systems that the shops now have to be out the expense and time of using an identifier before recovering to keep from spoiling a whole cannister of refrigerant. Now it is getting to the point that they will have to buy and use sealant detectors as well. That cost, of course, has to be passed on to their customers if they are to stay in business and continue to be able to afford shoes for the baby.

Have a great day,
