Wiper WPM 8x14x3,5/5 NBR+Stal

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

Design and operation:
The scraper is made of oil-resistant NBR rubber, housed in a steel casing that ensures secure and durable seating in the slot.
The construction is adapted for press-fit installation, guaranteeing strong retention even under intensive working conditions.
The flexible rubber lip closely adheres to the piston rod's 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 lubricants,
casing: steel – provides rigidity and secure mounting.
