Questions about this item
What does the 1 oz container size mean for treating a typical A/C system?
The 1 oz bottle treats one vehicle's R-1234yf cooling system by circulating through evaporators, condensers, hoses, gaskets, seals and O-rings to stop small leaks without polymers.
How does the R-1234yf compatibility affect which vehicles I can use this on?
This stop leak is formulated only for systems running R-1234yf refrigerant, so it matches newer trucks and cars that specify that fluid type.
What do I need to connect this product to the service port?
The liquid comes in a 1 oz box container; you will need a standard R-1234yf injection hose or adapter that fits your service port to introduce it.
