AY Wiper Seal
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.
In addition, the sealing lip facing the media reduces the residual oil film. 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 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 or
whenever the residual oil film is to be kept at a minimum.

Range of application
Double wiper rings profile AY are designed for axially operated rods in hydraulic and
pneumatic cylinders, lifters, and rod guidances.
|Operating temperature||-35 °C to +100 °C|
|Pneumatics||-35 °C to +80 °C|
|Sliding speed||≤ 2 m/s|
Ultrathan® 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 excels because of its increased heat resistance, improved against
hydrolysis, and lower compression set values.
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 wipedoff dirt falls off.
