This is an upgrade to the pressure gauge supplied with Canton Accusumps. One gauge size is used on all Accusump sizes and models. The standard gauge is not liquid-filled, but it is suitable for most applications. This liquid-filled gauge will stay accurate longer in high-vibration environments.
Note 1: Liquid-filled gauges are filled approximately 90% full of liquid. An air pocket must be left to allow room for the liquid to expand and contract with temperature changes. It is normal for the air pocket to be visible in the face of the gauge. This is not a defect!
Note 2: Gauge face design varies!
