Wiper WPM 50x58x5/7 NBR+Stal

The WPM wiper 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 rod surface from accelerated wear.

Structure and operation:
The wiper is made of oil-resistant NBR rubber, mounted in a steel casing that ensures secure and durable seating in the slot.
The design is adapted for press-fit installation, guaranteeing strong retention even under intensive working conditions.
The flexible rubber lip closely adheres to the rod surface, 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,
casing: steel – provides rigidity and secure mounting.
