Tire Pressure Gauge
 

This may seem trivial, but I need a GOOD tire inflation tool with a accurate gauge that also can control the air being added or released. I've look at several and none really do the job. Anybody that knows of a good one, let me know.

If you are looking for an accurate gauge, this is a 0.5% of full scale from 0 to 12 psig. You should be able to purchase through the manufacturer. I have calibrated a few of them and they are an accurate gauge. You would be able to connect it to a connector that has a Schraeder valve to bleed pressure.
