Wiper WPM 63x73x5/7 NBR+Stal

The WPM type scraper ring has been created to protect hydraulic cylinder glands from environmental contaminants.
Its function is to eliminate the risk of mud, water, or dirt entering the system, which allows the seals and piston rod surfaces to be protected from accelerated wear.

Construction and operation:
This ring is made from oil-resistant NBR rubber, which is embedded in a sturdy steel casing.
This construction ensures secure placement and fixation in the seat, as well as excellent retention even when operating in demanding conditions.
The flexible rubber lip closely adheres to the piston rod surface, effectively eliminating contaminants and excess moisture during actuator 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) – resistance to oils and greases,
casing: steel – provides stiffness and correct mounting.
