Wiper WPM 63,5x76,2x7,95/11,13 NBR+Stal

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

Construction and operation:
The scraper is made of oil-resistant NBR rubber, set in a steel case ensuring secure and durable fitting in the housing.
The design is adapted for press-fit installation, ensuring a strong hold even in high-intensity working conditions.
The flexible rubber lip adheres closely to the piston rod surface, effectively cleaning it of dirt and moisture during the actuator's working movement.

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

Materials:
working part: NBR (nitrile rubber) – resistance to oils and greases,
case: steel – provides rigidity and secure mounting.

Technical dimensions:
- internal diameter (d): 63.5 mm
- external diameter (D): 76.2 mm
- height / thickness (H): 7.95/11.13 mm

Size in inches: 2.5" × 3" × 0.313"/0.438"

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