Liquid Filled 2½" Tire Pressure Gauge Head Only

Product information

Everything needed to make a confident decision.

Tire pressure gauge head only 2-1/2” GID dial face 1/2 lb increments with 2% accuracy (1/4 lb increments on 0-15) PSI Options (choose above when ordering): 0-60 PSI by 1/2 lb 0-45 PSI by 1/2 lb 0-30 PSI by 1/2 lb 0-15 PSI by 1/4 lb 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. Gauge head only - bumper not included
