Hydraulic Cylinder Wiper Seals - Unfazed by Dirt
Wipers Protect Pneumatic and Hydraulic Cylinders From Contaminants
In pneumatic and hydraulic cylinders, wipers protect the interior of the cylinder against external contaminant, as the cylinder rod is retracting. Freudenberg Sealing Technologies (FST) offers the correct wiper for every kind of cylinder and application. These wipers offer maximum reliability and operating life, and can be customized with or without metal reinforcement, or as a double lip wiper with or without pressure relief.
Maximum Protection Through Precise Adjustment
Primary and secondary seals as well as the guides of modern sealing systems require reliable protection the use of wipers. Dirt, dust, moisture and other environmental influences must not contaminate the operating medium and must above all be kept away from the pressure-loaded sealing edges and other contact zones.
Freudenberg Sealing Technologies Wipers are precisely adjusted to the particular conditions of use and are impressive for their maximum protective effect.
