Safety Warning

Full Product Description

The wear-resistant Ultrathan® AF wiper seal / ring serves to prevent ingress of dust, dirt, sand and swarf into the hydraulic cylinder. This reduces the risk of scoring on the piston rod caused by external contamination embedded in the guidance. The good wiping effect is achieved by the special design of the wiper lip.

The proven P5008 polyurethane compound stands for abrasion resistance, minor permanent deformation and robustness against external mechanical impact. The wiper seal is securely held in place in the axially open groove via press-fit of the metal jacket vis-à-vis the inner groove diameter. As the wiper lip is flush with the cylinder head it is largely protected against external mechanical damage.


• Robust seal profile for harshest operating conditions.

• Extreme wear resistance.

• Suitable for fully automatic installation

• Dimensions according to DIN ISO 6195, Type B.

• Simple fabrication of the housing.


Range of application:

Hydraulic cylinders and valve tappets
