Ashcroft® series 500 and 501 large diaphragm seals are small enough to be used in compact spaces, but provide sufficient displacement to drive a wide variety of instrumentation. Their all-welded construction prevents possible process media leakage where fugitive emissions are a concern. They are commonly used for corrosive processes, processes with elevated temperatures, viscous process media, limited space, water treatment facilities, and where male connections are preferred.

Weksler Glass® series DW-T and DW-TF large diaphragm seals are used to prevent the process fluid from entering the instrument. The diaphragm is welded to the top housing of the diaphragm seal to allow for removal of the gauge and diaphragm assembly without loss of fill fluid.

Ashcroft® series 311 and 312 mini diaphragm seals are used in confined areas to protect pressure measuring instruments. Used to ensure process compatibility, they are also applied when process media exhibits high temperature and pulsation. They are commonly used in oil & gas, refineries, chemical & petrochemical, water & wastewater, oil & gas fracking, biogas & biodiesel, and NACE compliant processes. They are ideal where corrosion protection and limited spacing are essential.
