Stainless Case Liquid Filled Pressure Gauges with 1/4" Brass Center Back Mount have a plexiglass window and are silicone filled. Temperature range is from -40C to 65C. Gauge scales are in PSI and kPa. Pressure ranges from 30" Vacuum to 1000 PSI are available.
These gauges are ideal where vibration, corrosion, and pulsating conditions exist.
For best results:
Ensure gauges are stored and mounted upright to avoid leakage
Remember to prick a hole or cut the tip off the vent plug
When choosing a gauge, choose a pressure range that places the needle in the middle range of the gauge - between the ten o'clock and two o'clock positions.
Exceeding the maximum range of the gauge may result in permanent damage to the gauge.
