Wiper WPM 45x56x5/7 NBR+Stal

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

Structure and operation:
The wiper is made of oil-resistant NBR rubber, set in a steel casing ensuring secure and durable seating in the slot.
The design is adapted for press-fitting into the assembly, which guarantees 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 working movement of the cylinder.

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 – provides rigidity and secure mounting.

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