X-Rings have a double sealing function as compared to an o-ring and can be used in a wide variety of static and dynamic sealing applications.
The four-lobed design provides twice the sealing surface in comparison to a standard o-ring.
The double-seal action requires less squeeze to maintain an effective seal. This reduction in squeeze means less friction and improved seal life.
X-Ring parting lines are between the lobes, away from the sealing surface. This eliminates the issue of leakage often resulting from a parting line's irregular surface as found on an O-Ring.
X-Rings are also designed to outperform a standard O-Ring in rotary seal applications.
