Snubber

A pressure snubber is a device used to suppress (“snub”) excess force or rapid movement in mechanical systems. Pressure snubbers are designed to dampen the effect of pressure pulses and spikes to assure longer service life and readability of pressure measuring instruments in harsh applications. Offered in a choice of porous, piston or throttling designs; these units can handle a range of media, from air and other gases, to water, steam, gasoline and oils.

Pressure snubbers protect pressure gauges from the harmful effects of vibrations generated in a pressurized system with pulsations such as positive displacement pumps or compressors. The pressure snubber works by evening out pressure fluctuations. Snubbers do not alter the pressure of the process, but reduces the pulsation in the line, thereby improving the stability of the pressure measuring instrument reading, while extending the effective lifetime of the instrument.
