Diaphragm Seals
Reliable Isolation for Pressure & Vacuum Gauges

Our diaphragm seals are engineered to protect pressure and vacuum gauges from harsh or incompatible process media. Whether you're working with corrosive chemicals, slurries, viscous materials, or crystallising fluids, these isolation devices preserve gauge accuracy and lifespan by preventing media ingress.

Key Applications:

• Used with pressure gauges and test gauges where media protection is essential
• Suitable for corrosive, high-particulate, or solidifying process fluids
• Ideal for food, chemical, mining, and water treatment industries

Compatibility:

• Connects easily to most mechanical pressure and vacuum gauges
• Optional capillary extension for remote mounting

Temperature Ratings:

• Standard Range: 0°C to 100°C
• High-Temperature Version: Up to 300°C with HT silicone oil and extended neck or capillary tube

Why Use Diaphragm Seals?

• Prevents media from clogging or damaging gauge internals
• Improves instrument reliability in challenging environments
• Reduces maintenance and calibration frequency
