Another common problem with air compressor pressure regulators is that they can leak. If your regulator leaks, it may not be able to hold the pressure in your compressor. This can cause your compressor to overheat and even break down. In addition, if your regulator is leaking, you may need to replace the O-rings.

Replacing the diaphragm is a relatively simple fix that can restore accurate pressure readings. Another common problem with air compressor pressure regulators is that they can leak. If your regulator leaks, it may not be able to hold the pressure in your compressor. This can cause your compressor to overheat and even break down.

The air compressor leaks will continue, however, and this cycle will repeat. If the leak in the air regulator diaphragm is large enough, the compressor will run and run, but the pressure in the tank will never get to the normal cut-out pressure as much of the compressed air is leaking out of the pressure regulator.

Inaccurate pressure readings are another common issue with air compressor pressure regulators. If your pressure gauge is showing inaccurate readings, the diaphragm in the device is likely damaged. Replacing the diaphragm is a relatively simple fix that can restore accurate pressure readings.
