This product is a combination of 2 Enviro-Safe products into 1 for maximum cooling performance.  This will remove moisture in the A/C system.  Moisture can cause corrosion in the A/C system or the A/C to freeze up.
The other part of the product will reduce friction in system and provide colder air duct temps in most cases.
Compatible with any automotive refrigerant except ammonia and CO2
Drying agent

Proseal with Leak Detector
Finds and seals leaks in ac systems
1 can of Enviro-Safe 1234YF ProSeal with Leak Detector will treat 1 vehicle.
Forms a hard seal on metal, schrader valves, o’rings, gaskets, a/c condensers, evaporators, line sets and solder joints
Even though Proseal with Leak Detector for R1234YF 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 with Leak Detector for R1234YF in the system it will reseal the schrader.
Proseal with Leak Detector for R1234YF uses a precisely selected, fluorescent-yellow dye that is highly visible and is the same dye used by auto makers in car A/Cs
While the dye is highly visible, and in most cases, able to be seen with the naked eye, the use of a blacklight as well as UV glasses does make it much more visible.
Before replacing expensive parts and labor, try Enviro-Safe Proseal with Leak Detector!
For best results, use Enviro-Safe Prodry for R1234YF BEFORE using the Enviro-Safe Proseal with Leak Detector for R1234YF to remove any moisture in your system. Moisture is corrosive and no one wants that in their system!
The can itself has a R134 top on it as shown in the picture so you will need a hose with a R134 top tap (right handed thread) and R1234yf vehicle connection.
