Overview

The Marshall Instruments CW00100 is a silicone-filled shock-proof pressure gauge designed for reliable performance in demanding industrial environments. The 1.5-inch white dial with a red pointer provides clear, high-contrast readings across its 0-100 PSI range. The silicone fill serves a critical function: it dampens needle oscillation caused by vibration, pressure spikes, and pulsation, delivering stable and accurate readings in conditions where a dry gauge would produce erratic needle movement.

Built with a stainless steel case and bezel, the gauge resists corrosion from moisture, chemicals, and harsh environmental exposure. The 1/8" NPT center back connection is a widely used standard thread, making installation straightforward in pneumatic lines, hydraulic systems, compressors, and other pressurized equipment. Its compact size makes it well-suited for applications where mounting space is limited, though users should ensure the 1.5-inch dial provides sufficient readability for their specific installation distance and lighting conditions.

Pros & Cons

👍 Pros

  • Silicone filling dampens needle vibration for stable readings in high-vibration environments
  • Stainless steel case and bezel resist corrosion in wet or chemically exposed settings
  • Compact 1.5-inch dial fits in tight mounting spaces
  • White dial with red pointer provides high-contrast readability
  • Standard 1/8" NPT back connection ensures broad compatibility with existing fittings

👎 Cons

  • 1.5-inch dial can be difficult to read at a distance or in low-light conditions
  • 100 PSI maximum range limits use in high-pressure applications
  • Center back connection only — no bottom or panel mount options in this model
  • Small dial face leaves limited space between graduation marks, reducing precision of visual readings

Frequently Asked Questions

It reads from 0 to 100 PSI, displayed on a white dial with a red pointer for clear visibility.
The gauge case is filled with silicone fluid, which dampens the needle movement caused by vibration and pressure pulsation. This results in steadier, more readable pressure readings in environments with mechanical vibration.
It has a 1/8" NPT center back connection, which is a standard pipe thread fitting commonly used in pneumatic and hydraulic systems.
Both the case and bezel are constructed from stainless steel, providing corrosion resistance and durability in harsh or wet environments.
The dial is 1.5 inches in diameter, making it a compact gauge suited for installations where space is limited.
