Wiper WPM 80x90x7/10 NBR+Stal

The WPM-type wiper ring is designed to protect hydraulic cylinder gland seals from external contaminants.
It guards against the ingress of mud, water, and dirt into the system's interior, protecting seals and rod surfaces from accelerated wear.

Construction and operation:
The wiper is made of oil-resistant NBR rubber, set in a steel casing, ensuring a secure and durable fit in the housing.
Its design allows installation by driving it into the assembly, ensuring a strong hold even under difficult working conditions.
The flexible rubber lip precisely adheres to the rod surface, effectively removing contaminants and moisture during cylinder operation.

Applications:
hydraulic cylinder glands,
working 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 a secure fit.
