Safety Warning

Descripción completa del producto

The Q3 rod seal is a compact seal and consists of a fabric-reinforced backup element with a vulcanized rubber sealing part. Due to their radial preloading, the sealing lips reliably wipe off the liquid film even in low pressure conditions or non-pressurized movement of the rod.
At higher pressures or pressure peaks, the fabric-reinforced backup element prevents gap extrusion at the back of the seal.
As an FKM version the Q3 rod seal can be used as a high-temperature variant for TPU rod seals.

• Enhanced sealing performance in non-pressurized conditions.
• Robust seal profile for harshest operating conditions.
• Good wear resistance.
• Insensitive to pressure peaks.
• High extrusion resistance.
• Excellent media resistance in case of suitable compound selection.
• Installation in closed and undercut housings.
• Low compression set.

Range of application:
Mainly used for sealing plungers, piston rods and valve slides. Also suitable for valve spools and rotary unions for oil.
