Generac 0C3025 Oil Pressure Switch. Has 10 PSI oil pressure actuation. Switch is normally closed (N.C.) meaning when oil pressure is applied at 10 PSI or more, the switch will open and allow the generator to run. Has 1/4"-18 threads. Was used on many Air Cooled models from the later 1990's until around 2010 when they switched to the same sensor, but with push-on type connectors (0G6820). Either will work, but you would need to but off the connectors and crimp on your own ring style for this sensor to work. Should be installed using thread sealant (not included). Use extreme caution when tightening this sensor into the block as the threads are tapered and will crack the block if over-tightened. This will result in the engine block needing replacement!
Generac replacement parts will also usually fit the following Generac branded generators: Honeywell, Guardian, Siemens, Carrier, Watchdog, Centurion, & Bryant.
