Analog Pressure Gauge, 4 Inch Face, PSI Range, 1000 PSI Major Graduations, Minor Graduations

It comes silicone filled from the factory, so no extra steps needed on your end before putting it to work. The silicone fill helps dampen needle movement and protects the internals from vibration and pressure spikes. If you ever end up with a dry gauge from the same product line, there is a fill kit available separately under kit number 9046, but this one is ready to go out of the box.
