AF ULTRATHAN® Wiper with Metal Case

The profile AF Ultrathan® wiper ring serves the

purpose of preventing the penetration of dust, dirt,
sand, and metal swarf into hydraulic cylinders. This
reduces the risk of scoring caused by contaminants
from external sources imbedded in the sliding parts.
The excellent wiping effect is achieved by the
special design of the wiper lip.
The proven PU-compound P5008 stands for high
abrasion resistance, minor permanent deformation,
and robustness vis-a-vis external mechanical
impact. By means of a press fit of the metal scan
vis-a-vis the external diameter of the seal housing,
the wiper is securely held in place in the axially
open installation housing. Thanks to the flush end
fit of the wiper lip with the cylinder head the lip
enjoys a high degree of protection against damage
from external causes.
Profile AF provides a proper sealing end device
from an engineering point of view and, in
conjunction with our rod seals profiles B3 and BU
constitutes a sealing system that has been tried
and proven under the toughest field conditions.

Range of Application:
Hydraulic cylinders and valves
Working temperature: – 35 to + 100 °C
Surface speed: ≤ 2 m/s
Compound:
Standard material of the elastomer part is P5008, a
polyurethane based Parker compound with a hardness
of approx. 93 Shore A. In comparison with other
polyurethane materials currently available on the
market, it excels because of its increased heat
resistance, and improved performance against
hydrolysis.

Installation:
The profile AF Ultrathan® wiper rings are manufactured
with a slightly oversized outer diameter D, thus
ensuring a secure press fit in the groove DH8 after
installation. Any contact of the wiper lip with piston rod
eyes or other connecting parts should be avoided.

For special requirements (temperature, speed, use

in water, HFA or HFB fluids, etc.), please contact
our Consultancy Service, so that suitable materials
and/or designs can be recommended.

AG ULTRATHAN® Wiper with Metal Case

The profile AG Ultrathan® wiper ring serves the

purposeof preventing the penetration of dust, dirt,
and, and metal swarf at the spherical bearings of a
hydraulic cylinder rod end. This reduces the danger
of „scuffing“ on the swivel bolt as a result of
contamination from external sources. The excellent
wiping effect is achieved by the special design of the
wiper lip. Furthermore, the wiper lip opens up during
lubrication allowing excess lubricant to escape.
The proven PU-compound P5008 stands for high
abrasion resistance, minor permanent
deformation, and robustness vis-a-vis external
mechanical impact. By means of a press fit of the
metal scan vis-a-vis the external diameter of the seal
housing, the wiper is securely held in place in the
axially open installation housing. Thanks to the flush
end fit of the wiper lip with the swivel riveting jig the
lip enjoys a high degree of protection against
damage from external causes.

Range of Application:
Hydraulic cylinders and valves
Working temperature: – 35 to + 100 °C
Surface speed: ≤ 2 m/s

Compound:
C.

Installation:
The profile AG Ultrathan® wiper rings are manufactured
with a slightly oversized outer diameter D, thus ensuring
a secure press fit in the groove DH8 after installation. Any
contact of the wiper lip with piston rod eyes or other
connecting parts should be avoided.

For special requirements (temperature, speed, use in

water, HFA
or HFB fluids, etc.), please contact our Consultancy
Service, so
that suitable materials and/or designs can be
recommended.

AH ULTRATHAN® Double Wiper with Metal Case
AH ULTRATHAN®Double wiper is used for the
protection of cylinders against dirt and for the
improvement of the total sealing effect. Press-fit
installation prevents O.D. contamination while the
additional sealing lip works in conjunction with Parker
rod seals to provide redundant sealing for leakage
reduction. An aggressive wiping lip , facing the
environment, ensure the utmost performance in
contamination exclusion along with the rod.

Important: When using the AH wiper in conjunction

with other rod seals, It is important to select a rod seal
profile that enables pressure relief of fluid in to the
system, otherwise a pressure trap may form between
the wiper and rod seal. Suggest rod seal profiles are
BS,B3.
Range of Application：
Hydraulic cylinders, valves.
Working temperature: -35 °C to + 100°C
Surface speed: ≤ 2 m/s
Material :
Standard material of the elastomer part is P5008, a
polyurethane based Parker compound with a hardness of
approx. 93 Shore A.

Installation:
The profile AF Ultrathan® wiper rings are manufactured with a
slightly oversized outer diameter D, thus ensuring a secure
press fit in the groove DH8 after installation. Any contact of the
wiper lip with piston rod eyes or other connecting parts should
be avoided.

For special requirements (temperature, speed, use in water,

HFA or HFB fluids, etc.), please contact our Consultancy
Service, so that suitable materials and/or designs can be
recommended.

AY ULTRATHAN® Double Wiper（JIS）

The purpose of the profile AY Ultrathan® double lip wiper is to

prevent dust, dirt, grains of sand, and metal swarfs. This is
achieved by a special design which largely prevents scoring,
protects the guiding parts and extends the service life of the
seals. The profile AY double wiper ring closes the rod in the
direction of the cylinder. No special screwrings or brackets are
required for installation. No close tolerances and no metal
inserts are required. The wiper is supplied as a continuous ring
and can easily be pressed into the groove. In addition, the
sealing lip facing the media reduces the residual oil film. The
polyurethane compound ensures excellent properties with
regard to dry run, increased wear resistance, and extended
service life due to good resistance to ozone and radiation
caused by weather conditions. We recommend profile AY
Ultrathan® double-lip wiper when using PTFE rod seals OD.

Range of Application:
double wiper rings profile AY are designed for axially operated rods
in hydraulic and pneumatic cylinders, lifters, and rod guidances.

Working temperatures: – 35 to + 100 °C

for pneumatics + 80 °C
Surface speed: ≤ 2 m/s

Compound:
P5008 is a polyurethane-based Parker compound with a hardness
of approx. 93 Shore A. In comparison with other polyurethane
materials currently available on the market it excells because of its
increased heat resistance, improved against hydrolysis, and lower
compression set values.

Installation:
The profile AY double lip wiper ring can easily be snapped into
grooves of simple design. Any contact of the wiper lip with piston
rod eyes or other connecting parts should be avoided.
However, we recommend the wiper lip to be out-side the housing,
so that the wiped-off dirt falls off.

For special requirements (pressure, temperature, speed, use in

water, HFA or HFB fluids, etc.), please contact our Consultancy
Service, so that suitable materials and/or designs can be
recommended.

B3 ULTRATHAN® Rod Seal(JIS)

The profile B3 Ultrathan® rod seal is a lipseal which fits in

the groove. These seals may be used for all applications
where the physical properties of normal or fabric
reinforced elastomers are insufficient.

The main advantages are:

• Unusually high wear resistance.
• Insensibility against shock loads and pressure peaks.
• High resistance against extrusion.
• Low compression set.
• Suitable for hardest working conditions.
• Easy installation.

Range of Application:
Working pressure: £ 400 bar
Working temperature: – 35 to + 110 °C
Surface speed: £ 0,5 m/s
Medium: Hydraulic oils (mineral oil-based)

Mainly for the sealing of piston rods and plungers in

heavy duty applications in mobile and stationary
hydraulics. The dimensions mainly conform to the
requirements of ISO 5597/I and ISO 3320 for housing and
diameters respectively.

Compound:
The P5008 compound is a Parker material based on
polyurethane with a hardness of approx. 93 Shore A. Its
main advantages in comparison with other polyurethane
materials currently available on the market are the
increased heat resistance, the improved performance
against hydrolysis and the lower compression set.

Installation:
The seals should have an axial clearance (see columns H
and L). To avoid damage at the sealing lips, the seals
should not be pulled over sharp edges during installation.
Normally these seals may be snapped into closed
grooves. Where access is restricted special assembly
tools may be required. Proposals for the design of such
tools will be provided on request. Tolerance guidelines
H8/f7. At the back of the seal a larger gap »e« is
permissible.

For special requirements (pressure, temperature,

speed, application in water, HFA-, HFB-fluids etc.)
please contact our Consultancy Service, so that
suitable materials and/or designs can be
recommended.

BR ULTRATHAN® Rod buffer Seals

BR Profile, Premium Buffer Seal

The BR profile is a compact rod seal designed to act as a
buffer seal for the primary rod seal. As a buffer seal, the BR
profile provides the majority of the rod sealing performance
while allowing fluid to by pass onto and energize the primary
rod seal. Fluid located between the BR profile and the rod
seal will relieve back into the cylinder by flowing past the BR
profile’s flexible static side lip and slotted pedestals. This
relieving or check valve function allows the BR profile and
primary rod seal to work as a sealing system without the
danger of developing a pressure trap. As a sealing system,
the BR profile and primary rod seal provide optimal
performance in the most difficult applications.

Range of Application
Primarily for mobile hydraulic cylinders.

Temperature: -35C to 110°C

Pressure: ≤500bar ( peak 1000 bar)
Surface Speed: ≤ 0.5m/s

Compounds:
P5008 is a Parker material based on polyurethane with a
Shore A hardness of approx. 93.
Backup ring compound: Polyamide

*Alternate Materials: For applications that may require

an alternate material, please contact your local Parker Seal
representative.

 B7 ULTRATHAN® Piston Lip Seal(JIS)

The profile B7 Ultrathan® piston seal is a lipseal

which fits tightly in the groove. These seals may
be used for all applications where the physical
properties of normal or fabric reinforced
elastomers are insufficient.

Their main advantages are:

• Unusually high wear resistance.
• Insensibility against shock loads and pressure peaks.
• High resistance against extrusion.
• Low compression set.
• Suitable for the most severe working conditions.
• Easy installation.

Range of Application:
Working pressure: £ 400 bar
Working temperature: – 35 to + 110 °C
Surface speed: £ 0,5 m/s
Medium: Hydraulic oils (mineral oil-based)

Mainly for the sealing of pistons in heavy duty

applications in mobile and stationary hydraulics.

Compound:
The P5008 compound is a Parker material based
on polyurethane with a hardness of approx. 93
Shore A. Its main advantages in comparison with
other polyurethane materials currently available
on the market are the increased heat resistance,
the improved resistance against hydrolysis and
the lower compression set.

Installation:
The seals should have an axial clearance (see
columns H and L). To avoid damage at the
sealing lips, the seals should not be pulled over
sharp edges during installation. Normally these
seals may be snapped into closed grooves.
Where access is restricted special assembly
tools may be required. Proposals for the design
of such tools will be provided on request.

For special requirements (pressure,

temperature, speed, application in water,
HFA-, HFB-fluids etc.), please contact our
Consultancy Service, so that suitable
materials and/or designs can be
recommended.

Definition
The maximum gap "e", stated with the respective profile, stands for the maximum gap occuring between rod and guidance resp. between piston
and cylinder exhausting all tolerances and maximum excentricity.
Extend the connecting line d/D–S and P–τ to line ξ1 respect ξ2.Connect the two intersections and read on scale »e« (0,16 mm page
28 resp. 0,18 mm page 29) the allowable gap.

Conditions:
1. Surface quality according to our recommendations (see "General Installation Guidelines").
2. Lubricating fluids.

For special conditions, e. g. non-lub fluids, water, acids, alcalies, please contact our Consultancy Service.

The nomographs in our catalogues have been developed for the "worst case", that means pushing conditions (for the rod e. g. plunger
conditions, explanation see above) and softest material in the corresponding group (e. g. 85 Shore A for polyurethanes and 70
Shore A for NBR).
If the application is not in a pushing mode, the extrusion gap can be increased for 25 %.
If instead of a 85 Shore A polyurethane a 93 Shore material or instead of a 70 Shore NBR a 85 Shore material is used, the extrusion
gap can be increased another 15 % (intermediate values to be balanced).

Example 1．(page28)
d/D = Dynam diameter = 90 mm*
S = Cross-section = 7,5
P = Pressure = 315
T = Temperature b
= 80 ℃

Example 2．(Page 29)

d/D = Dynam diameter = 100*
S = Cross-section = *6 mm
P = Pressure = 100
T = Temperature b
= 80 ℃

** Insert the dynamic diameter and not the static one (groove dia. Or tight fit). Means cylinder diameter for the piston seal (D) and rod
diameter for the rod seal (d).

 General Installation Guidelines

International (ISO) and national (DIN) standards for seal housing dimensions are in place and should be considered. For seals requiring a special
groove, e. g. special seals, valve seals, rotor seals etc., the groove dimensions are stated separately. In general, the surface finishes, leading edge
chamfers and dimensions stated here have already proved themselves and will mostly be found in the standards.

We recommend that customers adhere to the tolerances and surface finishes stated in this catalogue. Only by working to these values will the
fitting of seals be made easy and assembly damage avoided.

Surfaces: Grinding as final machining process for dynamic sealing surfaces is not sufficient. These surfaces have to be polished
afterwards.

Radii: As for the necessary radii please refer to the respective profile data or the applicable standards.
