. I ordered 5 and all 5 seem to work adequately. Use them in air-cooled engines to measure oil pressure. Four of the five engines have clocked up almost 300 hours since installation and are still running. I'm guessing the values are in the few psi range, but I didn't test them against a calibrated source before I started using them. I will buy again.
