Wiper WPM 90x100x7/10 NBR+Stal

The WPM 90x100x7/10 NBR+Steel scraper ring is designed to protect 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 scraper is made of oil-resistant NBR rubber, mounted in a steel casing ensuring secure and durable seating in the housing.
The structure is designed to be embedded in the assembly, guaranteeing a firm hold even in demanding working conditions.
The flexible rubber lip tightly adheres to the piston rod surface, effectively cleaning it of dirt and moisture during the actuator's operational 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,
- casing: steel – provides rigidity and secure fastening.

Technical features:
- internal diameter (d): 90 mm
- external diameter (D): 100 mm
- height/thickness (H): 7/10 mm

Dimensions in inches:
- 3.54” × 3.94” × 0.28”/0.39”
