D-3 TYPE

D-3 is a single lip seal. It’s used primarily as seals for piston rods in hydraulic cylinders. U32i in polyurethane are proven elements, due to their good mechanical properties, for standard cylinder construction, particularly for mobile hydraulics under rough operating conditions.
Advantages
- Good pressure-adapted sealing effect
- Unaffected by high loads and deflections of the piston rod
- High resistance against extrusion.
- Lower friction in the low pressure range compared with double-lipped versions.
- Easy installation.
