Choosing a pressure gauge snubber

A snubber restricts rapid pressure changes before they reach the gauge. This can steady the indication on systems where pump or compressor operation causes pressure pulsation.

Restriction also affects response time. Choose an arrangement that reduces unwanted fluctuation while allowing the instrument to respond quickly enough for the task.

Browse all pressure gauge accessories or contact GNW for help matching the part to your installation.

Pulsation or mechanical vibration?

A snubber acts on pressure changes through the connection. A filled gauge dampens movement within the case. The right choice depends on what is making the pointer move.

Use the snubber's specified pressure and material limits; it is not a substitute for correctly rated equipment.

Pressure damping

Restrict rapid changes reaching the measuring element.

Response time

Balance a steadier reading against the speed of indication needed.

Connection fit

Match the gauge and process thread arrangement.

Applications

Snubbers can support the following tasks when selected for the duty.

Pump discharge

Reduce pulsation at a suitable pressure measuring point.

Compressor systems

Steady indication where cyclic pressure changes affect readings.

Hydraulic equipment

Select restriction and materials for the system fluid.

Maintenance improvements

Address pressure fluctuation after identifying the source.

How to choose

identify the fluctuation; match the connection; check the medium and rating; set the required response.

Identify the fluctuation

Check whether pressure pulsation is causing the unstable reading.

Match the connection

Confirm the thread form and size.

Check the medium and rating

Review material, pressure and temperature suitability.

Set the required response

Follow the product instructions for any available adjustment.

Frequently asked questions

Practical answers to help with selection and replacement.

What does a snubber do?

It restricts rapid pressure changes reaching a gauge, which can reduce pointer fluctuation.

Will it slow the reading?

Restriction can increase response time. Select it around how quickly the reading needs to change.

Is a snubber the same as a filled gauge?

No. A snubber acts through the pressure connection; liquid filling damps the gauge mechanism inside the case.

Does it protect against all overpressure?

No. The gauge and snubber must be rated for the duty, and additional protection may be required.
