Wiper WPM 32x40x5/7 NBR+Stal

The WPM wiper ring is dedicated to protecting the glands of hydraulic cylinders against external contamination. It protects against the ingress of mud, water and dirt into the system, which protects the seals and the piston rod surface against faster wear. Design and function: The wiper is made of oil-resistant nitrile rubber (NBR) mounted in a steel case that guarantees a stable and durable installation in the housing. The design is optimised for installation by press-fitting, which ensures a durable fit even under intensive use. The flexible rubber lip fits precisely against the piston rod surface, effectively removing dirt and moisture during cylinder movement. Application: hydraulic cylinder glands, working mechanisms of construction and agricultural machinery, systems exposed to mud, dust and water. Materials: Working part: NBR (nitrile rubber) – resistant to oils and greases, Case: steel – provides rigidity and stable fixing.
