Pressure Gauges
Shop pressure gauges for air compressors, air receivers and compressed-air systems, including standard, glycerine-filled and replacement gauges in a range of connection types, dial sizes and pressure ranges.
Air Compressor & Receiver Pressure Gauges
Pressure gauges provide a clear visual indication of pressure within compressors, receivers and compressed-air systems.
The current range includes standard dry gauges, glycerine-filled gauges and replacement options with different pressure ranges, dial diameters and connection arrangements.
Always match the full specification — pressure range, connection size, connection position and dial size — rather than choosing by appearance or thread size alone.

How to Choose the Correct Pressure Gauge
Pressure gauges can look almost identical while having different operating ranges, thread sizes, connection positions and dial diameters.
Pressure Range
Confirm the required working and gauge range before ordering.
Connection Size
Check whether the existing gauge uses a 1/8", 1/4" or another connection size.
Connection Position
Confirm whether a back-entry or bottom-entry gauge is required.
Dial Diameter
Gauges can use different dial diameters even where the thread and pressure range appear similar.
Standard vs Glycerine-Filled Pressure Gauges
Standard dry gauges are suitable for many general compressed-air applications.
Glycerine-filled gauges contain liquid around the internal mechanism. This helps damp needle movement where vibration or pressure pulsation would otherwise make the gauge harder to read.
Pressure Gauge Installation
- Safely isolate the compressor or system
- Fully depressurise the relevant equipment before removing the gauge
- Confirm the correct pressure range before installation
- Check connection size and thread arrangement
- Confirm back-entry or bottom-entry orientation
- Use a suitable sealing method for the threaded connection
- Do not tighten the gauge by applying excessive force to the case
- Check the completed connection for leakage

Pressure Gauge FAQs
How do I identify the correct replacement pressure gauge?
Check the pressure range, connection size, connection position, dial diameter and any existing manufacturer or part reference.
What pressure gauge sizes are available?
The current range includes selected 1/8" and 1/4" connection options, back-entry and bottom-entry gauges, plus 42mm, 50mm and 53mm dial sizes on selected models.
What is a glycerine-filled pressure gauge?
A glycerine-filled gauge contains liquid that helps damp needle movement caused by vibration or pressure pulsation.
Can I choose a pressure gauge from the thread size alone?
No. Check the pressure range, connection size, connection position, dial diameter and suitability for the intended application.
What is the difference between back entry and bottom entry?
A back-entry gauge connects through the rear of the gauge case, while a bottom-entry gauge connects underneath the case.
Can Compressed Air Systems UK help identify the correct gauge?
Yes. Provide the existing gauge reference, pressure range, connection size, dial size where relevant and clear photographs of the gauge and equipment.
Not Sure Which Pressure Gauge You Need?
