Nu-Calgon 4050-01 A/C EasySeal-SS

A/C EasySeal is designed to prevent as well as repair leaks anywhere in the system, including condensers, evaporators, copper lines, and soldered joints. It is easily injected into the system, traveling with the refrigerant, searching for leaks. The fact that A/C EasySeal travels with the refrigerant is very important to its ability to find leaks faster, using less sealant than those sealants designed to mix and travel with the systems oil.  
The A/C EasySeal circulates through the system with the refrigerant seeking out leaks rather than migrating slowly with the oil…keeping in mind that only a small portion of the system oil actually migrates with the refrigerant through the system.
A/C EasySeal will react with moisture or air that is naturally present at a leak, forming a secure seal. A/C EasySeal is compatible with the refrigerant, oil and all system materials and it will not react until it comes into contact with the air and moisture at the leak, forming a permanent seal.
A/C EasySeal is a time saver. It finds leaks quickly and seals them, saving the time and money required in searching for the smallest leaks. With A/C EasySeal, the contractor is able to just add a can to the system and be confident the leak has been fixed and move on to the next job.
In most cases, one can will seal systems that have lost all refrigerant in as little as seven days and is designed for large systems up to 5 tons. For systems 1.5 tons to fractional, use A/C EasySeal-SS. For commercial systems with refrigerant charge of 125 lbs. – 250 lbs., use A/C EasySeal-XL.
