About Pressure Gauges

High-Pressure Differential Gauges
These gauges are able to withstand line pressures up to 3,000 psi. They are commonly used to measure pressure differences in pumps and filters.
Gauges with 316 stainless steel case are more corrosion resistant than gauges with an aluminum case.

Tire Pressure Gauges with Indicator Bar
A bar slides out of the top of these gauges to display pressure reading.
Stainless steel gauges are more corrosion resistant than steel and brass gauges.
Gauges with a quick-disconnect tip press into the valve stem rather than clamping over it for a faster setup and more accurate readings.
