    A/C High/Low Pressure Safety Switch


    Protect your valuable factory A/C system with this high/low pressure switch kit. This simple, easy to install insurance policy simply installs between the expansion valve and the liquid hose that attaches to it. The harness has a pre-molded connector specifically designed to connect to the switch and is then spliced into the wire that leads to the compressor clutch.

    How does it work? When system pressure drops below 28psi, OR exceeds 380psi, on the systems high side, power is cut off to the compressor. This prevents damage to the system components, such as the compressor and hoses and the extensive labor that goes into flushing the system out after major compressor failures.

    If your air conditioning system is currently down, or if you are planning maintenance in the near future, it is HIGHLY recommended that you install this piece.

    Fits MOST mid 1960s to early 1970s General Motors cars & trucks.


    If you don't see your car or truck, or if you have any questions, please send us a message with your vehicle information. We may have a solution.

    Compatible with both R12 & 134a
