External & Internal Pressure Gauge Snubbers
CMI External & Internal Pressure Gauge Snubbers are precision-engineered to protect sensitive pressure instruments, transmitters, and switches from destructive hydraulic shocks, pneumatic pulsations, and sudden system surges. By integrating CMI’s proprietary sintered porous metal technology within the snubber body, these devices smoothly dampen violent fluid fluctuations before they reach downstream components, ensuring highly stable and accurate readings.
Porous Metal Pressure Dampening for Stable & Accurate Instrument Protection
CMI External & Internal Pressure Gauge Snubbers are designed to protect sensitive pressure instruments from hydraulic shock, pneumatic pulsation, and sudden pressure spikes commonly found in industrial process systems.
By integrating a precision porous metal element inside the snubber body, pressure fluctuations are effectively dampened before reaching downstream gauges, transmitters, switches, and analytical instruments.
This helps improve reading stability, extend instrument service life, and reduce failures caused by pressure surges or pulsation.
Manufactured using CMI sintered porous metal technology, these snubbers provide uniform permeability, excellent corrosion resistance, and stable flow restriction performance across a wide range of liquids and gases including oils, water, compressed air, process gases, and mercury systems.
Available in multiple media grades and connection sizes, CMI gauge snubbers can be customized for specific flow characteristics, operating pressures, and process conditions.
