Wiper WPM 55x65x7/10 NBR+Stal

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

Construction and operation:
The scraper is made of oil-resistant NBR rubber, set in a steel casing that ensures secure and long-lasting seating in the housing.
The design is adapted for press-fit installation, ensuring firm holding even under heavy-duty conditions.
The flexible rubber lip closely adheres to the 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) – oil and grease resistance,
casing: steel – ensures rigidity and secure mounting.

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