FlutterGuard™ virtually eliminates pointer flutter, making the gauge easier to read and reducing excessive movement wear. Liquid-free casing results in lighter weight and eliminates the chance of gauge leakage.

Fig. Inter. - Figure Interval. Increments between PSI numbers on gauge face.
Grad. Inter. - Graduation Interval. Fractional increments between PSI numbers on gauge face.
