Wiper WPM 55x63x5/7 NBR+Stal

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

Construction and operation:
The scraper is made from oil-resistant NBR rubber, set in a steel casing that ensures secure and durable seating in the housing.
The design is adapted for press-fitting into the assembly, guaranteeing a strong hold even under intense working conditions.
The flexible rubber lip closely adheres to the piston rod surface, effectively cleaning it of dirt and moisture during the cylinder's operating 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,
casing: steel – provides stiffness and secure mounting.
