Wiper WPM 65x75x5/7 NBR+Stal

The WPM wiper 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.

Construction and operation:
The wiper is made of oil-resistant NBR rubber, encased in a steel frame that ensures secure and durable seating in the housing.
The construction is designed to be driven into the assembly, guaranteeing a firm hold even under intensive working conditions.
The flexible rubber lip closely adheres to the piston rod surface, effectively cleaning 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) – oil and lubricant resistance,
frame: steel – provides rigidity and secure mounting.
