Wiper WPM 55x65x5/7 NBR+Stal

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

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

Applications:
hydraulic cylinder seals,
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 – provides rigidity and secure attachment.

Technical dimensions:
- inner diameter (d): 55 mm
- outer diameter (D): 65 mm
- height/thickness (H): 5/7 mm

Size in inches: 2.17" × 2.56" × 0.20"/0.28"
