Wiper WPM 6x12x5/7 NBR+Stal

The WPM scraper 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 piston rod surface from accelerated wear.

Construction and operation:
The scraper is made of oil-resistant NBR rubber, housed in a steel casing ensuring secure and durable seating in the nest.
The construction is adapted for press-fit installation, ensuring a strong hold even under intensive working conditions.
The flexible rubber lip closely adheres to the piston rod surface, effectively cleaning it of dirt and moisture during the cylinder's working motion.

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 – ensures rigidity and secure fastening.
