Wiper WPM 80x90x5/8 NBR+Stal

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

Construction and Function:
The scraper is made of oil-resistant NBR rubber, set in a steel casing that ensures secure and durable positioning in the housing.
The design is adapted to be embedded in the assembly, guaranteeing a strong hold even in high-intensity working conditions.
The flexible rubber lip fits snugly against the rod surface, effectively cleaning it of dirt and moisture during the cylinder's working motion.

Applications:
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 construction and easy installation,
durable seating in the housing,
mechanical resistance.
