Wiper WPM 42x52x7/10 NBR+Stal

The WPM type wiper ring is designed to protect hydraulic cylinder glands from external contaminants.
It prevents mud, water, and dirt from entering the system, protecting seals and the rod surface from accelerated wear.
Construction and Function:
The wiper is made from oil-resistant NBR rubber, set in a steel housing ensuring a secure and durable fit in the seat.
The design is adapted for press-fit installation, guaranteeing solid holding even under intense working conditions.
The flexible rubber lip closely adheres to the rod surface, effectively cleaning it of dirt and moisture during the cylinder's operational movement.
Application:
hydraulic cylinder glands,
work 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 – provides rigidity and secure mounting.
