Our all stainless steel pressure gauges are manufactured with fully stainless construction — including the case, wetted parts and internal components — providing exceptional corrosion resistance, durability and hygienic suitability for demanding industrial environments.

Designed for use in food & beverage production, pharmaceutical processing, petrochemical plants and marine applications, these gauges offer long-term reliability in aggressive or high-humidity conditions where standard brass-internal gauges may not be suitable.

Why Choose an All Stainless Steel Pressure Gauge?

Unlike standard gauges that use brass or alloy internal components, all stainless models provide:

• Superior corrosion resistance in chemical and washdown environments
• Improved temperature tolerance
• Hygienic compatibility for cleanrooms and sanitary zones
• Longer service life in aggressive media
• Professional appearance for visible installations

These gauges are ideal where durability and material compatibility are critical.

Pressure Ranges & Connections

Our stainless steel gauges are available in a wide range of pressure scales including:

• Vacuum ranges
• Compound gauges
• Low pressure applications
• Standard industrial ranges (e.g. 0–6 bar, 0–10 bar, 0–16 bar, 0–25 bar, 0–40 bar and higher)

Connection options include 1/8", 1/4", 3/8" and 1/2" BSP, NPT and specialist fittings to suit your system.

Maintenance & Serviceability

Gauges 50mm and above feature a removable bezel, allowing easier recalibration or servicing where required. This makes them particularly suitable for facilities operating maintenance schedules or quality systems.

Calibration certificates can be supplied on request for customers requiring traceability.

Typical Applications

All stainless steel gauges are commonly used in:

• Food & beverage processing lines
• Pharmaceutical and cleanroom environments
• Chemical dosing systems
• Marine and offshore installations
• Steam and sterilisation equipment
• Process control panels

Selecting the Right Stainless Steel Gauge

When choosing a gauge, consider:

• Dial size (visibility vs space constraints)
• Pressure range
• Media compatibility
• Mounting orientation
• Vibration level (dry vs filled)

If you're unsure which specification is suitable, our technical team can advise.
