Liquid Filled Tire Pressure Gauge...............
I trying to find a liquid fillled tire pressure gauge that will read 80 psi. Longarce racing sells a nice one but it only reads to 60 psi. http://www.longacreracing.com/catalo...d=1118&catid=8
At Last... A Liquid Filled Tire Gauge That Works Right!
2 1/2" 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 equalize pressure and maintain gauge accuracy
Liquid filled gauges have many advantages. But they can change readings by as much as 2-3 psi if the temperature changes...
All pressure gauges - liquid filled and regular - need to be vented to the outside to read accurately. If not vented, as the surrounding temperature changes, they will build up pressure inside and affect the accuracy - by as much as 2-3 psi!
But if a liquid filled gauge is vented it will leak on your hands and in your tool box. Some manufacturers aren't aware of this and don't vent the gauge. You then have to deal with the variation in accuracy.
Now from Longacre comes the simple answer to this problem. We have installed a specially designed pressure equalizer button on the top of the gauge. Before you use the gauge just push this button. Instantly any temperature-caused pressure difference will be eliminated and you will be guaranteed the most accurate readings possible.
If you have a liquid filled tire gauge prove it to yourself. Take your gauge that has been in a cool place and in the typical range you use. Then take the gauge and put it out in the sun for about 45 minutes, as would happen during a race. Then re-check the tire that is still in the cool place. You will see that the reading has changed. You know that the pressure in the tire is the same so the gauge reading must now be off. How will this affect your handling to have tire pressures high or low by several psi? What's worse is that you don't know at what temp the gauge is actually correct! It depends on the temp in the factory when it was manufactured. You could remove the rubber fill plug on the gauge. But then the liquid would leak out.

Well I know + or - a few psi in our truck tires would be undetectable, but on the race track that is a different story. I was looking for a nice accurate gauge that I could bring to the track and also use it on my truck. Unfortunately I was not able to find a liquid filled gauge with any psi higher then 60. After doing some research I did find a place that sells gauges up to 160 psi (not liquid filled) but made in the USA with a lifetime warranty with a few different options to choose from. I received it today and I'm very happy with it. Here is the link.
http://www.getagauge.com/ I got the H series with the 160 psi. They recommend using a gauge where the desired PSI should be in the middle of the gauge range. http://www.getagauge.com/faq.cfm#pressure
