Codes
The following seal compound and body material
compatibility chart is provided as an aid in selecting a
specific synthetic rubber compound or body material for
a particular application. Operating and environmental
conditions must be considered when making the
selection of a quick coupling.
Refer to the appropriate section of the catalog for
Ordering Information for Seal Codes for specific
products. ­
To indicate a special material just add the appropriate
code letter as a suffix to the catalog number of the
coupler.
It is not necessary to use the code “STD” as the standard
Nitrile seal will be used when another code is not used.
For recommendations for media not listed below, please
contact your Parker representative or the factory.
Note
This chart is intended as a guide only and is not be
considered as a recommendation to use Parker quick
action couplings in a specific application or with a
specific fluid, other factors that must be considered
include but are not limited to: fluid and ambient
temperature, system pressure, both operating and peak,
frequency of connect and disconnect, and applicable
­
standards or regulations.
