With Quad-Rings ®/X-Rings the standard grooves are deeper in comparison with O-ring glands. So the diametrical sqeeuze is lower than with O-rings. This makes dynamic sealing possible with reduced friction.
The four lips of the Quad-Ring ®/X-Ring create more sealing capacity and at the same time a groove for lubrication, which, is very favorable for dynamic sealing.
The most important advanctage of the Quad-Ring ®/X-Ring is the high stability for dynamic applications. In the situation that an O-ring rolls in the groove and creates torsion, Quad-Ring ®/X-Ring will slide with nog negative results.
More resistant to spiral failure.
