Other picks

  • Avoid

    Leak Saver

    “the leak saver refrigerant is indeed flammable and it has a nice blue flame like you'd expect from natural gas or propane. I definitely wouldn't recommend using this type of refrigerant in your AC system of your vehicle unless it's specifically designed for flammable gas.”

  • Avoid

    ZeroR

    “Just like the leak saver, the ZeroR is also some sort of natural gas and has a blue flame. Probably not a good idea to use a leak saver or the ZeroR in an air conditioning system with a leak.”
