Wiper WPM 65x85x7/10 NBR+Stal

The WPM type wiper ring is designed to protect hydraulic cylinder glands from external contaminants. It prevents mud, water, and dirt from entering the system, safeguarding seals and the piston rod surface from accelerated wear.
Construction and operation: The wiper is made of oil-resistant NBR rubber, set in a steel frame, ensuring a secure and durable fit in the housing. The design is suitable for press-fit installation, guaranteeing a strong hold even in demanding working conditions. The flexible rubber lip closely adheres to the piston rod surface, effectively removing contaminants and moisture during cylinder operation.
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, frame: steel – provides rigidity and secure fitting.
