Wiper WPM 57,15x66,68x5/7 NBR+Stal

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

Construction and operation:
The scraper is made from oil-resistant NBR rubber, set in a steel casing that ensures secure and durable fitting in the housing.
The design is adapted for embedding, guaranteeing a firm hold even under intensive working conditions.
The flexible rubber lip adheres precisely 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,
casing: steel – ensures rigidity and secure attachment.

Technical part:
- internal diameter (d): 57.15 mm
- external diameter (D): 66.68 mm
- height/thickness (H): 5/7 mm

Dimensions in inches for gland seals: 2.25 x 2.625 x 0.197/0.276 inches.
