Pressure Snubber Explained

A snubber uses a porous disc, a piston or a small orifice to slow the flow of fluid into the instrument. Fast spikes are smoothed while the steady pressure still reaches the gauge.

Snubbers suit pump discharges, compressors and hydraulic systems. Porous types can block in dirty service; adjustable needle types allow tuning.

Frequently Asked Questions

What is a Pressure Snubber?

A pressure snubber is a restriction fitted before a gauge or switch to damp pulsation and pressure spikes.

Snubber or liquid filled gauge?

Both help. Filling damps the pointer and movement; a snubber limits the pressure spike reaching the element. Severe service often uses both.

Does a snubber slow the reading?

Yes, slightly. Choose the damping so real pressure changes are still seen in time.
