Hydraulic cylinders are used in a wide range of applications and environments, including those with dust, debris, or extreme weather. Wiper seals (also called as scrapers, excluders, or dust seals) are installed on the exterior surface of the cylinder head to prevent pollutants from entering the cylinder assembly and hydraulic system.
When the equipment is stationary (no reciprocating motion of the piston rod) and in operation (dynamic, reciprocating rod), hydraulic wiper seals maintain sealing contact with the piston rod, whilst the rod seal determines the rod diameter d tolerance. The retracting piston rod might convey impurities into the cylinder without a wiper seal.
The wiper seal's outer static sealing within the housing is also critical to prevent moisture or particles from penetrating around the wiper seal.
Single Acting Hydraulic Wiper Seal - WS10
The WS-10 is a single-action wiper seal that keeps foreign particles out of hydraulic systems, preventing wear and damage to all internal components, including seals. For particular applications requiring high temperatures, the WS-10 is offered in NBR, PU, and FKM.

Double Acting Hydraulic Wiper Seal - WS-D14
Double Acting Hydraulic Wiper Seal - WS-D14 acts with a wiping function of a U-ring, and a wiping action outwards against soiling.
Strong wiping action against dirt
Very good sealing effect against residual film of oil on the extending rod
The double-acting design offers optimum contamination resistance while also maximizing performance in conjunction with the rod seal. To prevent pres..
Double Acting Hydraulic Wiper Seal - WS-D15
Double Acting Hydraulic Wiper Seal - WS-D15 acts with a wiping function of a U-ring, and a wiping action outwards against soiling.
The WS-D15 is a double-acting double wiper that prevents foreign particles from entering hydraulic cylinders. The lip is built in such a manner that it reliably sweeps away dirt while leaving an oil film on the rod. The second lip serves a dual purpose, removing debris from the rod a..
Single Acting Hydraulic Wiper Seal with metal case - WS-20
This is a single-acting wiper. Because it is pressed against the rod, dirt is wiped from the surface by the action of the rod as it retracts. On the outer diameter, a metal caged ring is vulcanized onto the elastomer body. These hydraulic wipers are made from a hard nitrile material chemically bonded to a corrosion-resistant carbon steel shell. As with other press-in wipers, there is no need for addi..
