AV wiper seal
The AV wiper protects the hydraulic system against, dust, dirt, moisture and other environmental influences.
The moulded dirt shield on the wiper prevents the migration of moisture underneath the wiper in the groove. The common occurrence of corrosion in the groove can thus be avoided. In applications with a vertically positioned piston rod head the dirt shield to protect the seal groove is particularly effective. Water running down the piston rod is diverted and does not enter the wiper groove. Due to the press fit in the housing and the pressure relief drill hole the risk of the wiper being pushed out of the cylinder housing is minimised.
Robust seal profile for harshest operating conditions.
Extreme wear resistance.
Excellent media resistance in case of suitable compound selection.
Suitable compounds available for special requirements of the chemical process industry.

Range of application
The AV wiper can be used in all hydraulic cylinders and is particularly well-suited for mobile applications.
|Operating temperature||-35 °C to +100 °C|
|Sliding speed||≤ 2 m/s|
The profile AV 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.
A ring-shaped area for improved abutting of the dirt shield should be provided at the front side of the cylinder.
