Wiper WPM 45x56x7/10 NBR+Stal

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

Design and operation:
The scraper is made from oil-resistant NBR rubber, housed in a steel casing ensuring secure and durable seating in the groove.
The design is adapted for press-fit installation, which guarantees strong retention even under intensive working conditions.
The flexible rubber lip fits snugly against the piston rod surface, effectively cleaning it of dirt and moisture during the cylinder's working motion.

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

Materials:
working part: NBR (nitrile rubber) – resistant to oils and greases,
casing: steel – provides rigidity and secure mounting.
