Wiper WPM 70x80x7/10 NBR+Stal

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

Construction and operation:
The wiper is made of oil-resistant NBR rubber, set in a steel casing ensuring secure and durable seating in the housing.
The design is adapted for insertion into the build, ensuring a strong hold even under intense 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 movement.

Application:
hydraulic cylinder glands,
operational 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.

Advantages:
effective protection against contamination,
simple construction and easy installation,
durable seating in the housing,
mechanical resistance.
