Wiper WPM 80x100x12/15 NBR+Stal

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

Construction and operation:
The scraper is made of oil-resistant NBR rubber, embedded in a steel casing that ensures secure and durable fitting in the housing.
The design is adapted for a press-fit installation, guaranteeing a strong hold even under intensive working conditions.
The flexible rubber lip closely adheres to the piston rod surface, effectively cleaning it of dirt and moisture during the cylinder's working movements.

Application:
- hydraulic cylinder glands,
- operational mechanisms of construction and agricultural machinery,
- systems exposed to mud, dust, and water.

Materials:
- working part: NBR (nitrile rubber) – resistance to oils and greases,
- casing: steel – ensures rigidity and secure attachment.

Advantages:
- effective protection against contaminants,
- simple construction and easy installation,
- durable retention in the housing,
- mechanical resistance.
