The self-retaining Ultrathan® EN rod seal/wiper ring for piston rods of pneumatic cylinders performs two functions: sealing and wiping.
The Ultrathan® compound is characterized by extremely high wear resistance.
The dirt shield formed at the wiper prevents moisture from migrating underneath the seal into the groove. As a result, corrosion which frequently occurs inside the groove can be avoided. In addition, due to the absence of undercuts and dead spaces, the assembly space in front of the seal is easy to clean. This makes the EN seal/wiper ring particularly well suited for food and pharmaceutical production and for all other applications requiring easy- to-clean components.

• Bi-functional element: seal and wiper.
• Robust seal profile for harshest operating conditions.
• Extreme wear resistance.
• No risk of corrosion since the combined retainer and wiper part eliminates the need for additional wire circlips.
• Long service life due to coordinated geometries of the functional lips and compound selection.
• Smooth running due to optimum lubricant-retaining sealing lip geometry.
• Excellent media resistance in case of suitable compound selection.
• Suitable compounds available for special requirements of the food processing industry.
• Identical housing for E7, E8, E9, EU, EF, EN, EW and ET.
• Installation in open housings.
• Low compression set.
• The coordinated geometries of the seal and wiper lips achieve favorable friction coefficients and long service life.
• Product geometry prevents dirt deposits at the front face of the cylinder.
