Hi.can an air pressure guage be used for oil pressure as well?regards,Brian.

 

Yes. I've adapted my Freon gauges to test the oil pressure in automatic transmissions.
Whether YOUR air pressure gauge will survive this, I don't know.

 

Many thanks!

 

as long as you understand the pressure capabilities of the gauge and the system under test.

 

Hi thanks,it on a diesel engine?

 

Coolant system pressure? Oil pressure? Fuel injector pressure? Fuel pump pressure? Brake line pressure?
Whatever it is, look up the proper pressure so you don't blow up your gauge.

 

Hi,the oil pressure,regards,Brian
