Wiper WPM 63x73x7/10 NBR+Stal

The WPM type wiper ring is designed to protect hydraulic cylinder glands from external contaminants.
It prevents the ingress of mud, water, and dirt into the system, protecting seals and piston rod surfaces from accelerated wear.

Construction and operation:
The wiper is made from oil-resistant NBR rubber, encased in a steel housing ensuring secure and durable seating in the groove.
The construction is adapted to be pressed into the housing, guaranteeing a firm hold even under intensive working conditions.
The flexible rubber lip closely adheres to the piston rod surface, effectively cleaning it from dirt and moisture during the cylinder's operational movement.

Application:
hydraulic cylinder glands,
working mechanisms of construction and agricultural machines,
systems exposed to mud, dust, and water.

Materials:
working part: NBR (nitrile rubber) – resistance to oils and lubricants,
housing: steel – ensures rigidity and secure mounting.
