Diaphragm Seals

Diaphragm Seals protect pressure gauges, switches, transmitters, and controls by isolating the instrument from harsh process media. Products in this category span compact seals, stainless steel bodies, PTFE or Teflon options, Viton options, flushing connections, and designs used where corrosive or difficult media could damage pressure instruments.

Applications include:

• Corrosive liquid and gas pressure measurement
• Viscous, dirty, or crystallizing media isolation
• Gauge, transmitter, and pressure control protection
• Flushable installations that need cleaning or maintenance access

Choose diaphragm seals by matching the process media, pressure range, fill fluid, seal material, connection, flushing need, and protected instrument.
