Our general purpose pressure gauges are designed to provide reliable and cost-effective pressure measurement for everyday industrial and commercial applications. Manufactured with robust metal cases and brass or alloy internal components, these gauges offer dependable performance in standard hydraulic, pneumatic, water and general process systems.

Ideal for workshops, plant equipment, HVAC installations, compressors and OEM machinery, general purpose gauges are suited to environments where media compatibility with brass internals is appropriate and extreme corrosion resistance is not required.

Why Choose a General Purpose Pressure Gauge?

General purpose pressure gauges provide:

  • Reliable and accurate pressure indication for routine industrial use
  • Cost-effective performance for standard applications
  • Durable construction for typical plant and workshop environments
  • Clear, easy-to-read dials in a range of sizes
  • Wide compatibility with air, water, oil and non-aggressive media

These gauges are ideal where practicality, affordability and dependable performance are key considerations.

For corrosive, hygienic or washdown environments, consider our
All Stainless Steel Pressure Gauges.
