Descripción completa del producto

The self-retaining ET Ultrathan® seal/wiper for flattened piston rods of non-rotating pneumatic cylinders is the oval counterpart of the round standard EU profile. It performs two functions: sealing and wiping.
The Utrathan® material is characterized by extremely high wear resistance.

• Due to application-optimized geometry and compounds suitable for use in oiled as well as in oil-free air (after initial lubrication on assembly).
• Bi-functional element: seal and wiper.
• 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.
• Identical housing for E7, E8, E9, EU, EF 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.

Range of application:
For flattened rods of pneumatic cylinders protected against rotation.

The ET rod seal/wiper is available in the following compounds:
P5008 - Industrial applications
P5009 - Industrial applications/low temperatures
P5000 - Food applications (FDA approval)
P5001 - Bio-degradable media
