Air Pressure Gauges

Buy a standalone gauge when you only need to monitor pressure. A control panel makes more sense when you also need switches or valves to add and release air from one or more circuits. The current {{website}} assortment includes both standalone gauges and combined gauge/control panels, so match the part to whether you need monitoring only or monitoring plus adjustment.

A dash-mounted gauge is better when you need to see pressure while driving or adjusting the system from the cab. A tank-mounted gauge is useful for checking reservoir pressure directly at the air tank during setup or service. Choose the mounting location first, then confirm the fitting type, gauge diameter, illumination needs, and pressure range.

A single-needle gauge is enough when you are monitoring one air circuit or tank. A dual-needle gauge is useful when two circuits need to be viewed independently, such as left and right air springs. If the gauge is part of a control panel, also check whether the switches and pneumatic connections match the way your system is plumbed.

Choose a range that covers the normal operating pressure of the air-suspension, onboard-air, or air-horn system without putting the expected reading at the extreme end of the scale. The current {{website}} assortment includes gauges and control panels for different pressure ranges, so compare the system maximum pressure with the gauge rating before ordering.
