Liquid Filled Tire Pressure Gauges
ALL liquid filled gauges are purposely filled to just 80%. The remaining 20% air pocket helps allow for thermal expansion and contraction as ambient temperature changes, thereby maintaining accuracy. If the gauge were filled to 100% even the slightest temperature change would significantly affect gauge readings as the expanding fluid would have no place to go. To give you even further accuracy over a wide operating range these Longacre gauges have a Special Vent Valve on the top of the gauge. A quick turn of the knob allows you to totally equalize internal and external pressures, guaranteeing the best accuracy possible.
