Our 40mm general purpose pressure gauges are compact, cost-effective instruments designed for installations where space is limited but reliable pressure indication is required. Manufactured with durable metal cases and brass wetted parts, these gauges are suited to standard hydraulic, pneumatic and water applications.

The 40mm dial size is ideal for small machines, air compressors, workshop equipment and OEM installations where a larger 63mm or 100mm gauge would be impractical. Despite their compact size, these gauges provide dependable pressure measurement for everyday industrial use.

Available in multiple pressure ranges including vacuum, compound and standard industrial scales (e.g. 0–6 bar, 0–10 bar, 0–16 bar and higher), options include:

  • Bottom entry (radial) and back entry (axial) connections
  • Dry versions as standard
  • BSP and NPT thread configurations

All gauges are suitable for general industrial use, and calibration certificates can be supplied on request.


What are 40mm general purpose gauges used for?
Compact hydraulic systems, pneumatic equipment, air compressors and OEM machinery.

Are they suitable for outdoor use?
They are suitable for sheltered installations. For corrosive or washdown environments, consider stainless steel alternatives.
