Wiper WPM 40x46x5/8 NBR+Stal

The WPM type wiper ring is designed to protect the hydraulic cylinder gland from external contaminants.
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, encased in a steel frame that ensures a secure and durable fit in the housing.
The construction is designed for press-fit installation, guaranteeing a strong hold even under intensive operating conditions.
The flexible rubber lip adheres closely to the piston rod surface, effectively cleaning it of dirt and moisture during the cylinder's working movement.

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,
frame: steel – provides rigidity and secure mounting.
