A: We do not have a way to cross reference different manufacturers and are unable to tell if this will work with your compressor.

the 4-1823-L1 pressure switch. I assume it is piped to the air compressor tank via a 1/4 inch copper line to sense tank pressure. Is that via the unloader port or another I cannot see on the www?
A: The 1/4" pipe thread port on the bottom of the switch is directly connected to a port of the same size on the tank. The unloader port is connected with copper tubing to the output line of the compressor before the check valve as it enters the tank. This way the line pressure is bled off when the motor stops allowing for easier starting again when the switch activates as tank pressure decreases.
