38471579 is a pressure switch conversion kit that replaces part number 56288764 if you are running the Ingersoll Rand 2475 value package compressor. This kit includes a replacement pressure switch, copper unloader tube, and pressure gauge.

Please note 38471579 will only work with the value package 2475N5-V and 2475N7.5-V compressors. If your compressor has an air cooled aftercooler and low oil level switch you have the premium package compressor. The conversion kit for the premium package 2475N compressor is 38471561.

IR changed pressure switch manufacturers in approximately 2009. The on/off switch and unloader valve are now on the opposite side of the older version switch. The old pressure switch part number was 56288764. This conversion kit provides all parts necessary to successfully convert your switch to the newer version. If instead you are running an Ingersoll Rand 2475 reciprocating compressor manufactured after 2010, you are able to purchase the 23474653 switch separately (link and relate 23474653)

The pressure switch turns the compressor on when it hits the lower pressure setpoint and turns the compressor off when the upper setpoint is reached. This is an OEM switch from Ingersoll Rand. Plenty of aftermarket switches are sold online, but many of them are not rated for the full load amp draw of the compressor and will cause pre-mature wear to the switch. The OEM switch from Ingersoll Rand is rated for a higher amp draw and is much heavier duty compared to others.

If you find your pressure switch is constantly leaking out of the unloader line, you should consider changing the check valve instead 85582229.
