Fluid Compatibility
This chart indicates the suitability of various elastomers and metals
for use with fluids to be conveyed. It is intended for use with
Danfoss couplings and should not be used to determine
compatibility for other products. It is intended as a guide only and
is not a guarantee. Final selection of the proper seal or material of
metal components is further dependent on many factors
including pressure, fluid and ambient temperature, concentration,
duration of exposure, etc.
How to Use the Chart
1. Both the elastomer and the metal must be considered when
determining suitability of combination for a coupling.
2. Locate the fluid to be conveyed and determine the suitability of
the elastomeric and metal components according to the
resistance rating shown for each.
3. Dimensional and operation specifications for each coupling
can be found on the catalog pages.
4. Information on seal options for couplings, and how to specify
them, are shown in the respective sections of this catalog.
5. Be sure to check the table below for maximum operating
temperature range of the elastomer desired.
6. For further details on the products shown in this catalog, and
their applications, consult your Danfoss Sales Representative or
Danfoss Technical Support.
7. Coupling component materials may differ from body material.
Refer to specific catalog pages.
Resistance Rating Key
E = Excellent – Fluid has little or no effect
G = Good – Fluid has minor to moderate effect
C = Conditional – Service conditions should be described to
Danfoss for determination of suitability for application
U = Unsatisfactory
The differences between ratings “E” and “G” are relative. Both
indicate satisfactory service. Where there is a choice, the materials
rated “E” may be expected to give better or longer service than
those rated “G”.
