Emzone A/C Dye Charge, 12a, 4-oz

The Emzone A/C Dye Charge, 12a, 4-oz, fixes leaky A/C systems. It works as a leak stopper for your air conditioning unit's metal and rubber parts. The dye seeps into even tiny cracks and seal leaks, improving your A/C's efficiency for colder air and lower bills. The dye is safe for all A/C systems, won't clog anything up or restrict flow, and can remain inside indefinitely. Simply add this 4-ounce bottle to trace even minor leaks in units from 2 to 5 pounds, whether the system is running or turned off. This leak detection dye is great for fixing evaporators, condensers, driers, O-rings, and gasket joints.
