This is a concentrate, not an aerosol.
Forms a hard seal on metal, schrader valves, o’rings, gaskets, a/c condensers, evaporators, line sets and solder joints
Enviro-Safe ProSeal repairs minor leaks in home, heat pump and industrial applications
Applications: any large or small system, home, industrial, walk-in coolers, walk-in freezers, heat pumps, grocery stores, hotels, boats, etc.

Even though ProSeal can form a seal on the schrader valve, when you hook up to it the seal will release and allow you to use the schrader if necessary. If there is still ProSeal in the system it will reseal the schrader.
You must have an injector tool to install this item. If you need an injector tool, we do have them available on this site. Look for #5055, #5060 or #5130.
If there is moisture in the system, you need to pull a vacuum or you can use the Enviro-Safe ProDry 8 oz concentrate.
The reason for the vacuum or the use of Enviro-Safe ProDry 8 oz concentrate is that it will eliminate moisture in the system. Moisture causes corrosion and nobody wants that in their system!
If the system will operate for at least 24 hours, ProSeal 8 oz concentrate and ProDry 8 oz concentrate may seal the leak.
If using the Enviro-Safe ProDry 8 oz concentrate with the ProSeal 8 oz concentrate, it is not necessary to pull a vacuum
Concentrate is the least expensive option per ounce
Can be measured out in individual doses
Must have an injector for installation
