We Developed a Pressure Control Radiator Cap
Application No.: 106137232 Patent No.:M473322
The most common radiator cap problem is aging. The internal rubber packing and springs get worn easily and radiator filler neck components from different brands have different sizes. It would leak out if it is not tight enough. So we improve it.
The features of a pressure control radiator cap are: prevention of making water leakage, and enough pressure. We developed that can be composed as accessories and the washer can be installed by yourself.
First, the radiator cap needs to be pressurized, and you can counterclockwise open the female. Second, putting the washer (0.5m/m) into the female and bolted and pressurization is done.
