Wiper WPM 50,8x60,33x4,78/7,14 NBR+Stal

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

Construction and operation:
The wiper is made of oil-resistant NBR rubber, set in a steel housing that ensures secure and durable seating in the groove.
The design is suitable for press-fit installation, ensuring a strong hold even under heavy-duty conditions.
The flexible rubber lip closely adheres to the piston rod surface, effectively cleaning it from dirt and moisture during the cylinder's working movement.

Applications:
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,
housing: steel – ensures rigidity and secure mounting.
