ABSOLUTELY NOT!!

First of all, bars leak is for cooling systems, not air conditioners.

Any type of sealer in the AC system will contaminate the entire system and any shop's equipment that is attached to it. It will gum up the whole system beyond repair. You need to replace the leaking component with all related services required when the system is opened.
