High Performance Seals for Extreme
Aerospace Environments
Sealing Solutions for Aerospace
The equipment that moves today’s industry is more reliable
and highly engineered than ever before. That’s why Parker
develops and manufactures engineered sealing solutions –
technologically advanced sealing devices and materials
that can keep pace with aggressive chemicals, high
temperatures and high and low pressures.
Our sealing products have our unique combination of
experience and innovation built right in, and we’re able to
supply them quickly and cost effectively to fit virtually any
application you can think of.
Diamond Seals
• Parker Diamond Seals,
designed for face sealing
applications, provide robust
sealing with retention while
requiring a fraction of the
space and load of traditional
seals.
Tadpole Tapes
• High temperature, flame-
resistant tadpole tapes from
Parker are used in firewall
closures and structural
sealing. Resilient, non-
hardening materials can be
customized for temperature
exposure and bolting force to
suit requirements.
FlexiSeals – Spring Energized PTFE
Seals (Air Management Systems)
• FlexiSeals® from Parker
Praedifa used in cabin air
conditioning systems
withstand temperatures up to
+260° C (500° F), are resistant
to dynamic movements and
meet the long lifetime
expectations of the industry.
Custom Rotary Shaft Seals for
Aerospace
• Parker's wide range of rotary shaft
seal options provide superior
elastomer lip material options for
improved wear resistance and
enhanced performance. Custom
and standard solutions are
available in a wide range of
elastomeric, PTFE or labyrinth
designs for engine, air
management, landing gear &
wheel and brake applications.
Custom Expansion Joints
• Custom expansion joints from
Parker manage movement,
vibration and misalignment
between ducting and mating
surfaces in aerospace air
management systems.
VX065
• O-rings made from VX065
deliver the extreme low
temperature performance
needed at high altitudes and
during engine startup. With
outstanding compression set
resistance, VX065 significantly
extends seal life in low
temperature fuel applications
where traditionally only
fluorosilicone could be used.
FF200
• Parker's ULTRA FF200
exceeds AMS 7257C,
demonstrating superior
retention of mechanical
properties and resistance to
compression set after longer
term fluid exposure and high
temperature.
Metal Seals (Jet Engines)
• Metal seals used in jet engines
withstand temperatures up to
1100° C (+2000° F) and
pressures up to 6200 bar while
ensuring extremely low
leakage rates.
Sealing Systems for Hydraulic
Actuators (Landing Gear)
• Parker Praedifa provides a
wide range of sealing systems
for hydraulic actuators
providing excellent
compatibility with common
aerospace fluids and
withstanding temperatures
down to -50° C (-58° F).
VMQ, PVMQ Extruded Profiles
• Parker's expertise in custom
extruded and spliced seals
enables highly complicated
geometries and shapes such
as 3-D, multi-corner and
compression-limited gaskets,
while providing superior high
bond integrity. This
customized solution does not
require tooling, and the seals
are devoid of parting lines,
flow lines, flash and void.
Fabric Reinforced Products
• Increase material strength with
low closure force sealing to
create a variety of products
including bellows, profile seals
and aerodynamic seals.
