Frequently Asked Questions

Is the 36878379 pressure switch compatible with my Ingersoll Rand compressor?

The 36878379 is an Ingersoll Rand engine oil pressure switch used on compatible portable air compressors including P185, P250, XP185 and related models. Always verify 36878379 in the compressor parts manual and confirm the model and serial number before ordering. Not sure? Reach out with your compressor model and serial number and we’ll help confirm compatibility. 

What does the 36878379 pressure switch do?

The 36878379 monitors engine oil pressure.

Its purpose is to help the machine determine whether adequate engine oil pressure is present during operation.

If oil pressure falls below the switch threshold, the compressor's protection system can respond to help protect the engine from damage caused by insufficient lubrication.

Why is engine oil pressure important?

Engine oil pressure is necessary to circulate lubricant through critical engine components.

Proper oil pressure helps protect:

  • Bearings
  • Crankshaft surfaces
  • Camshaft components
  • Other moving engine parts

Loss of oil pressure can quickly cause severe engine wear or failure.

What are the signs that the 36878379 pressure switch needs to be replaced?

Common signs that the 36878379 engine oil pressure switch may be failing include:

  • Compressor shuts down for low oil pressure even when actual engine oil pressure is normal
  • Machine will not stay running after startup
  • Low oil pressure shutdown occurs intermittently
  • Switch remains in the wrong electrical state when adequate oil pressure is present
  • Engine protection circuit does not respond when oil pressure is genuinely low
  • Wiring terminal is loose, corroded, burned, or damaged
  • Oil leaks from around the switch body
  • Switch shows inconsistent continuity during testing

These symptoms can also be caused by actual low engine oil pressure, low oil level, damaged wiring, a failing oil pump, or other engine problems, so actual oil pressure should be verified before replacing the switch.

Is this an OEM part?

This is an OEM-equivalent replacement pressure switch designed to meet the same performance standards as the original Ingersoll Rand switch.  

How difficult is it to install?

Replacing the 36878379 is generally an easy to moderate electrical and mechanical repair.

Before replacement:

  • Shut the compressor down completely
  • Disconnect the battery and prevent accidental startup
  • Allow the engine to cool
  • Clean the area around the switch
  • Label or photograph the electrical connection
  • Be prepared for a small amount of engine oil at the switch port

Installation generally involves disconnecting the electrical terminal, removing the old pressure switch, installing the replacement 36878379 using the correct sealing method, reconnecting the wiring, and checking for oil leaks and proper shutdown-circuit operation.

Someone familiar with routine diesel-engine or portable-compressor maintenance can generally perform the repair without major machine disassembly.
