THREADED OFFLINE NON-METALLIC DIAPHRAGM SEALS

REOTEMP’s Threaded Offline Non-Metallic Diaphragm Seals are designed with an upper and lower housing bolted together with a Teflon or Viton diaphragm bonded to the upper housing. This design allows for the lower housing to be removed for easy cleanout of the seal chamber while still maintaining the system fill. The Teflon and Viton diaphragms are ideal for protecting the pressure instrument from corrosive process fluid.

  • Removable Lower Housing Design for Easy Cleanout
  • Wide Variety of Plastic and Metallic Lower Housing Materials
  • Highly Sensitive and Corrosion Resistant Diaphragm
  • High Displacement Diaphragms Ideal for Mechanical Differential Pressure Gauges and Low Pressure Gauges
