Hydraulic Wiper Seal

PU seals refer to Polyurethane-based seals, commonly used in hydraulic systems for dynamic and static sealing due to their excellent wear resistance and elasticity.

Description:

• Purpose: Provide tight sealing in both dynamic (moving) and static (fixed) applications.

• Material: Made from Polyurethane (PU), which has high mechanical strength, elasticity, and resistance to abrasion.

• Types:

  • Rod and piston seals

  • Wiper seals

  • Buffer seals

• Operating Conditions:

  • Pressure: Up to 400 bar

  • Temperature: -40°C to +100°C (some types up to +120°C)

  • Speed: Suitable for high dynamic applications

Applications:

• Construction machinery

• Agricultural equipment

• Industrial hydraulic cylinders

• Injection molding machines

Advantages:

• High abrasion resistance

• Excellent mechanical properties

• Long service life

• Good chemical and oil resistance
