ProSeal & ProDry with Leak Detector is perfect for finding and sealing those pesky leaks, and with the added Prodry, it will turn that moisture into oil!  Prodry features a dehydrating agent that converts system moisture into a synthetic oil to stop and prevent acid formation in your system while also increasing cooling performance.
1 can of Enviro-Safe 1234YF ProSeal ProDry with Dye will treat one 
vehicle.
This product is pressurized.
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 and R1234yf vehicle connection.
