Hydraulic wiper, imperial, polyurethane, T421, 17.463 x 24.054 x 2.718 mm, Hallite.

The 421 snap-in rod wiper has been designed for light to medium duty applications. The proportions of the wiping lip ensure that contact is maintained with the surface of the rod to remove contaminants. The moulded ribs on the internal diameter provides extra stability to the seal and help prevent pressure trapping. The outside diameter contacts the housing diameter and has a sealing lip to prevent moisture entering the groove.
