Wiper WPM 40x50x7/10 NBR+Stal

The WPM scraper ring is designed to protect hydraulic cylinder gland seals from external contamination.
It prevents the ingress of mud, water, and dirt into the system, safeguarding the seals and the rod surface from accelerated wear.

Construction and operation:
The scraper is made from oil-resistant NBR rubber, mounted in a steel frame ensuring secure and durable seating in the housing.
The construction is designed for press-fit installation, guaranteeing a strong hold even under intense working conditions.
The flexible rubber lip closely adheres to the rod surface, effectively cleaning it from dirt and moisture during the cylinder's working movement.

Application:
hydraulic cylinder glands,
operating mechanisms of construction and agricultural machinery,
systems exposed to mud, dust, and water.

Materials:
working part: NBR (nitrile rubber) – oil and grease resistance,
frame: steel – provides rigidity and secure fixing.
