Wiper WPM 70x80x5/7 NBR+Stal

WPM type wiper ring (70x80x5/7 NBR+Stal) is designed to protect hydraulic cylinder glands from external contaminants.
It prevents mud, water, and dirt from entering the system, protecting the seals and the rod surface from accelerated wear.

Construction and working principle:
The wiper is made of oil-resistant NBR rubber, set in a steel frame to ensure secure and durable installation in the housing.
The design is intended for drive-in mounting, guaranteeing firm holding even in demanding conditions.
The flexible rubber lip closely adheres to the rod surface, effectively cleaning it of dirt and moisture during the cylinder's working movement.

Applications:
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 – ensures rigidity and secure mounting.
