Our 40mm all stainless steel pressure gauges are compact, corrosion-resistant instruments designed for installations where space is limited but durability is essential. Manufactured with stainless steel cases and wetted parts, these gauges provide excellent resistance to moisture, chemicals, and harsh industrial environments.

The 40mm dial size is ideal for use on small hydraulic systems, pneumatic equipment, compressors, OEM machinery, and process panels where a larger 63mm or 100mm gauge would be impractical. Despite their compact size, these gauges deliver reliable and accurate pressure indication across a wide range of applications.

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 or glycerine-filled versions for vibration resistance
• BSP and NPT thread configurations

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

If you require assistance selecting the correct pressure range or connection type, our technical team can provide guidance to ensure you choose the most appropriate 40mm stainless steel gauge for your application.

What are 40mm stainless steel pressure gauges typically used for?
