Wiper WPM 57,15x69,85x7,95/11,13 NBR+Stal

The WPM type scraper ring is used to protect hydraulic cylinder glands from external contaminants.
It prevents mud, water, and dirt from entering the system, thus protecting the seals and piston rod surface from accelerated wear.

Construction and operation:
The scraper is made from oil-resistant NBR rubber, placed in a steel casing, ensuring secure seating in the housing.
The design is suitable for embedding in construction, providing stability under intensive working conditions.
The flexible rubber lip adheres to the surface of the piston rod, effectively cleaning it of dirt and moisture during the cylinder's working movement.

Applications:
hydraulic cylinder glands,
mechanisms in construction and agricultural machinery,
systems exposed to mud, dust, and water.

Materials:
working part: NBR (nitrile rubber) – resistant to oils and greases,
casing: steel – provides rigidity and secure mounting.
