Wiper WPM 75x85x7/10 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 interior, protecting seals and the rod surface from accelerated wear.

Construction and operation:
The wiper is made from oil-resistant NBR rubber, set in a steel casing that ensures secure and durable fitting in the housing.
The design is adapted for press-fitting into assembly, allowing for a firm hold even under intensive working conditions.
The flexible rubber lip closely adheres to the rod surface, effectively cleaning it of dirt and moisture during the cylinder's working movement.

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