Diaphragm Seals


Diaphragm Seals

For Demanding Industrial Applications

If your application involves harsh conditions, such as extreme temperatures, it is important to protect your equipment’s pressure instruments—including gauges, transmitters, pressure switches, and more. To do this, you need a seal that performs and withstand its environment. In these situations, a diaphragm seal—sometimes referred to as a gauge isolator or a chemical seal—can seal off the pressure gauges and switches and isolate them from any harmful process fluids. The diaphragm seal protects the process fluid from coming into contact with the sensor and:

  • Prevents fluid accumulation—as well as clogging and crystallization—in the instruments
  • Prevents corrosion and minimizes contamination
  • Protects against bacteria development
  • Protects the pressure instruments from extreme temperatures
