Wiper WPM 45x55x5/7 NBR+Stal

The WPM type scraper ring is designed to protect the hydraulic cylinder glands from external contamination.
It prevents mud, water, and dirt from penetrating into the system, protecting seals and the surface of the piston rod from accelerated wear.

Construction and operation:
The scraper is made of oil-resistant NBR rubber material, embedded in a steel frame, ensuring a secure and durable fit in the slot.
The design is adapted for press-in installation, which guarantees strong holding in demanding working conditions.
The flexible rubber lip adheres perfectly to the surface of the piston rod, effectively cleaning it of dirt and moisture during the cylinder's working movement.

Application:
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,
frame: steel – provides rigidity and secure mounting.
