Wiper WPM 45x57x7/10 NBR+Stal

The WPM type scraper ring is designed to protect the gland seals of hydraulic cylinders from external contamination.
It prevents mud, water, and dirt from entering the system, protecting the seals and piston rod surface from accelerated wear.

Construction and operation:
The scraper is made from oil-resistant NBR rubber, housed in a steel casing ensuring secure and durable fitting in the socket.
The design is suited for press-in installation, guaranteeing strong retention even under intensive working conditions.
The flexible rubber lip closely adheres to the surface of the piston rod, effectively cleaning it of dirt and moisture during the cylinder's operational movement.

Applications:
hydraulic cylinder glands,
working mechanisms of construction and agricultural machines,
systems exposed to mud, dust, and water.

Materials:
working part: NBR (nitrile rubber) – oil and grease resistance,
casing: steel – provides rigidity and secure attachment.
