Wiper WPM 50,8x69,85x6,35/9,53 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 piston rod surface from accelerated wear.

Construction and operation:
The scraper is made of oil-resistant NBR rubber, embedded in a steel housing, ensuring a secure and durable fit in its seat.
The design is adapted for press-fitting, 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 motion.

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,
- housing: steel – ensures rigidity and secure mounting.

Technical data:
- internal diameter (d): 50.8 mm
- external diameter (D): 69.85 mm
- height/thickness (H): 6.35/9.53 mm

Size in inches:
- for gland seals and universal: 2 x 2.75 x 0.25/0.375 (inches)
