Wiper seal

O-ringcircularNBR

Wipers prevent the entry of dust and dirt particles when the piston rod is retracted. They protect not only the sealing system from damage but also the hydraulic fluid from contamination. In addition, double-acting wipers also retain an excess residual oil film. Thanks to their press fit, wipers with metal housings are particularly suitable for heavy external contamination. The Dichtomatik product brand portfolio offers a wide variety of wipers, which can be used in many hydraulic cylinders. Benefits at a Glance Single- and double-acting variants for open and closed installation spaces Different profiles for standardized installation spaces Wear resistant and therefore good lifetime Good resistance against oils, lubricants, greases and hydraulic fluids Very good price-performance ratio Suitable for many industrial applications Important note: Dichtomatik products comply with common industrial standards and therefore are suitable for many applications excluding safety-critical ones like Automotive. Premium Freudenberg products are the right choice for all applications ensuring highest quality and safety standards and therefore optimal total cost of ownership.
