1) The roughness of the surface in contact with the medium is <R
a
0.8 μm (31.5 μin). Reduced surface roughness levels are available on request.
2) Material AISI 316/316L (combination of AISI 316 for required pressure resistance and AISI 316L for required chemical resistance (dual rated))
3) Product Configurator order code for "Process connection"
4) The sealing surface in these process connections is smaller than what is specified in the standard. Due to the smaller sealing surface, a special
seal must be used. For further information, please contact a seal manufacturer or your local Endress+Hauser Sales Center.
