Wiper WPM 40x50x5/8 NBR+Stal

The WPM wiper ring is designed to protect the glands of hydraulic cylinders from external contaminants.
It prevents mud, water, and dirt from entering the system, protecting seals and the rod surface from accelerated wear.

Construction and operation:
The wiper is made of oil-resistant NBR rubber, set in a steel casing that ensures a secure and durable fit in the housing.
The design is adapted for installation by pressing into the housing, guaranteeing a strong hold even under intense working conditions.
The flexible rubber lip adheres closely 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) – oil and grease resistance,
casing: steel – ensures rigidity and secure mounting.
