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 Sections A (Pneumatics), B (Hydraulics) and C
(
Diagnostics) 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.
