Magellan International All-Purpose Leak Stop has been specially formulated to stop small leaks in evaporators and condensers as well as around gaskets and seals. Unlike some competitive leak-stop formulations, Magellan International All-Purpose Leak Stop does not contain any polymers. Polymer-based formulations have the tendency to harden, clogging critical components and leading to expensive repairs. Magellan International All-Purpose Leak Stopis designed for safe use in most automotive AC systems.
