Full Product Description

The E5 rod seal is a U-ring specifically designed for use in pneumatic applications. The dimensions of the standard range conform to the rod diameters according to ISO 3320 or CETOP RP 52 P, RP 43 P and RP 53 P. The E5 rod seal is available in both Ultrathan® and rubber compounds. The Ultrathan® variants are characterized by extremely high wear resistance and resistance against pressure peaks.

• Due to application-optimized geometry and compounds suitable for use in lubricated as well as in oil-free air (after initial lubrication on assembly).
• Robust seal profile for harshest operating conditions.
• Good wear resistance.
• Long service life thanks to application-optimized compounds.
• Smooth running due to optimum lubricant-retaining sealing lip geometry.
• Easier installation.
• High temperature resistance in case of suitable compound selection.
• Excellent media resistance in case of suitable compound selection.
• Installation in closed and undercut housings.

Range of application:
Mainly used for pneumatic cylinders.

The E5 rod seal is available in the following compounds:
N3578 - General purpose
P5010 - Heavy-duty
P5009 - Heavy-duty and low temperatures
V3681 - High temperatures
N8602 - Low temperatures
N3510 - Expanded temperature range (high and low)
E3676 - General purpose
