Liquid Filled Gauges

Liquid filled tire gauges have many advantages but they can change readings by as much as 2-3 psi if the temperature changes.

Now from Longacre comes the simple answer to this problem. We have installed a specially designed pressure equalizer valve on the top of the gauge. Before you use the gauge just loosen the knob on top of the gauge 1/4 turn, then hand retighten. Instantly any temperature-caused pressure difference will be eliminated and you will be guaranteed the most accurate readings possible.
