General Technical
Standard O-Rings supplied with Parker tube fittings and
adapters are 90 durometer hard nitrile (Buna-N) Parker
compound #N0552 or similar. These O-Rings are well suited
for most industrial hydraulic and pneumatic systems. They
have high extrusion resistance making them suitable for very
high pressure static applications. Optional high temperature
fluorocarbon, Parker compound #V0894, is also available
for higher temperature specifications.
O-Rings for other than normal hydraulic media or
higher temperature applications can be selected from
the following chart. The chart should be used only as
a general guide. Before making final selection for a
given application, it is recommended that appropriate
tests be conducted to assure compatibility with the fluid,
temperature, pressure and other environmental conditions.
For fluids not shown in the chart, please contact the Tube
Fittings Division or Parker Seal Group.
