  • Common Questions


    Where is this manufactured?


    I wish I had done a better job of buying American made products.


    How do I purchase it?


    You should order it.


    What is the size of the larger valves in the kit?


    The larger ones are listed in the specifications, but you should read the description in the Amazon offering to get a better idea of the size.


    What is the difference between the 2 r134a valves?


    The green are made of a material called Viton which is made to resist harsh chemicals and otherwise breakdown conventional black rubber o-rings/seals.


    Will any of the valves in the kit be able to replace the valve in the a/c low pressure port on my BMW x3?


    This is dependent on the weather.
