The Parker Prädifa Ultrathan® rod seal is a U-ring with an interference fit on the outer diameter. It is
extremely wear-resistant, ensures reliable load holding performance, and is suitable
for high-pressure applications in hydraulics.

Range of application
Mainly for sealing piston rods and plungers in heavy-duty mobile and stationary hydraulics applications. The range of dimensions is primarily oriented to the requirements of ISO 5597 and ISO 3320 for housings and diameters.
Operating pressure ≤ 400 bar
Operating temperature -35 °C to +110 °C
Sliding speed ≤ 0.5 m/s
Media Hydraulic oils based on mineral oil

Compounds
The Ultrathan® P5008 compound is a Parker Praedifa material based on polyurethane with a hardness of approx. 93 Shore A. Its main advantages in comparison with other polyurethane materials currently available on the market are the increased heat resistance and the lower compression set. For media containing water, we recommend our hydrolysis resistant polyurethane compound P5001.

Other compounds:

P5075, P5007, P 5070, P5011, P5080,. P5012, P4300, P5500, P5004, P5000, P5009, P6062, P6000

• Robust seal profile for harshest operating conditions.
• Extreme wear resistance.
• Easier installation.
• Insensitive to pressure peaks.
• High extrusion resistance.
• Excellent media resistance in case of suitable compound selection.
• Suitable compounds are available for special requirements of the chemical process industry.
• Suitable compounds are available for special requirements of the food processing industry.
• Dimensions according to ISO 5597.
• Installation in closed and undercut housings.
• Low compression set.
