Diaphragm Seals
Diaphragm Seals
Available Models
  • Type C Series for Sanitary Applications
    These quick-couple, one-piece seals are designed to meet 3A standard requirements for sanitary piping in food, beverage, pharmaceuticals, and other industries.

  • Type E Series
    The Mansfield & Green EW Series Diaphragm Seals are miniature seal elements designed for operations in new construction and MRS applications.

  • Type L Series for Low Pressure Applications
    For demanding low-pressure applications, the Type L Series elements provide users with a cost-effective solution. These seals feature a removable elastomer diaphragm for pressure ranges from 29" Hg vacuum to 1,250 psig at 100°F (88 bar at 38°C).

  • Type R Series with Removable Metal
    Used in general purpose applications, this seal element has a removable metal diaphragm. Ideal for applications from 15 to 2,500 psig at 100°F (1 to 176 bar at 38°C), these elements feature a diaphragm that is easily replaced by the user. These seals are available in a variety of diaphragm materials.

  • Type S Series General Purpose Elements
    Economical seal incorporates a diaphragm welded permanently to the top housing. Welded metal seals are ideal for general-purpose applications with ranges from 15 to 2,500 psig at 100°F (1 to 176 bar at 38°C).

  • Type SCE Series for Tank Applications
    This particular type of seal is ideal for applications where piping or insulation requires extension of the diaphragm into the flow-stream of the process media. They are also suitable for tank level applications.

  • Type SCW Series for Fugitive Emissions
    Designed for applications requiring control of fugitive emissions, toxic and explosive media, these all welded seals are available with ranges from 10 psig to Class 300.

  • Type SF Series Flush Flange
    Mansfield & Green SF Series seal elements feature a one-piece, all welded construction with an integrated raised face ANSIB16.5 class flange seal, surface machined into the upper housing.

  • Type SMJ and SNJ Series for Jacketed Pipelines
    These seal elements are used in applications where there is a jacketed pipeline and where heated or cooled processes are involved. The Type SMJ conforms to Schedule 40 process pipe rating (other schedules available). Type SNJ seals meet ANSI flange pressure/temperature ratings.

  • Type ST Series for Low Pressure
    Type ST Series is specifically designed to protect electronic transmitters, DP transmitters, transducers, and low pressure gauges against process media damage in a wide variety of process control and pipeline applications. Ideal for transmitter applications where closed systems require high sensitivity, this series provides superior accuracy where greater volumetric displacement is required.

  • Type T Series for Corrosive Applications
    These seal elements feature a TEFLON diaphragm that is field replaceable. They are ideal for corrosive applications with ranges from 0 to 10 psig at 100°F (0.8 to 176 bar at 38°C). These seals are suitable for applications with a temperature range of -40 to 400°F (-40 to 204°C).

  • XR-Series All-welded Process Gauge and Diaphragm Seal
    AMETEK’s XR-Series All-welded Gauge and Seal offers customers a lower cost alternative to an individual gauge and diaphragm seal with the added benefit of a reduction in potential leaks and double containment.
