Flush Flanged


Flush Flanged seals incorporate an integral flange into the seal design. Both the size and pressure class of the process connection is required at time of quotation.

Materials of Construction:

Diaphragms are welded to 316 stainless steel body.

Both carbon steel and 316 stainless steel ANSI flanges are available on the Flush Flanged seal type.


Solid state and TIG welding of the diaphragm allows for the manufacture of diaphragm seals with a variety of diaphragm materials.

Diaphragm cavity design allows for vacuum filling while providing support for the diaphragm membrane.

Flushing/Calibration rings are also available on the Flush Flanged seal family.

Best Practice:

Flush Flanged seals are best suited for use on flanged process connections 2 inch and larger and all pressure classes.

For smaller flanged process connection sizes please refer to the OffLine Flanged style seals.
