The Generac 0G6820 has been made obsolete and the replacement oil pressure switch can now be found below. It is a direct replacement for the old style switch.
Generac 0L2917C Oil Pressure Switch
Generac 0G6820 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. Same sensor as 0C3025, however instead of screw on terminals, this has 1/4" push on terminals. 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.
