X-rings / Quad®-rings
X-rings or Quad®-rings are self-sealing, double acting sealing elements with a symmetrical four-lip profile used for static and dynamic applications. X-rings require in comparison to an O-ring a lower pre-pressing. Therefore the friction and the wear is reduced. The four sealing lips provide a higher sealing performance. The main advantage of the x-ring is its stability in dynamic applications, because it doesn’t tend to twist in the groove.
