Wiper WPM 76,2x88,9x7,95/11,13 NBR+Stal

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

Construction and operation:
The wiper is made of oil-resistant NBR rubber, set in a steel housing ensuring secure and durable seating in the slot.
The design is adapted for press-fitted installation, which guarantees a strong hold even under intense working conditions.
The flexible rubber lip adheres closely to the piston rod surface, effectively cleaning it of dirt and moisture during the actuator's operating 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) – resistance to oils and greases,
housing: steel – ensures rigidity and secure mounting.
