2.5" Liquid Filled Tyre Gauge 0-60PSI

• 2.5" Deluxe Gauge with protective bumper
• Holds pressure reading until released
• Glow-in-the-Dark dial face
• 17" hose with swivel ball chuck
• Specially designed vent button to equalise pressure and maintain gauge accuracy

A specialised vent mechanism has been incorporated to ensure pressure equalisation and uphold gauge precision. While liquid-filled gauges offer numerous benefits, they are susceptible to fluctuations in readings of up to 2-3 psi due to temperature changes.

Regardless of whether they are liquid-filled or standard, all pressure gauges necessitate external venting to maintain accuracy. Without proper venting, temperature shifts in the environment can cause pressure build-up within the gauge, leading to inaccuracies of up to 2-3 psi.

However, traditional venting methods for liquid-filled gauges can result in leakage, posing inconvenience and potential mess. Some manufacturers overlook this issue and release gauges without proper venting, thereby introducing variations in accuracy.

Longacre has introduced a straightforward solution to this dilemma. By integrating a specially designed pressure equaliser button at the gauge's apex, users can rectify temperature-induced pressure differentials with a simple push before taking readings, ensuring utmost accuracy.

To illustrate the significance of this innovation, consider conducting a test with your liquid-filled tire gauge. Begin with the gauge stored in a cool environment within your typical usage range. Then, expose the gauge to sunlight for approximately 45 minutes, simulating conditions encountered during a race. Upon rechecking the tire pressure, discrepancies in readings will be apparent, despite the pressure remaining constant. This discrepancy not only impacts handling but also raises uncertainty regarding the gauge's accurate temperature calibration, which is contingent upon factory conditions during manufacture. While removing the rubber fill plug could potentially address this issue, it risks leakage of the gauge's liquid contents.
