Quad Rings Quad-Rings®, also known as X-Rings, 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. Quad-Ring parting lines are between the lobes, away from the sealing surface, thus eliminating the problems of leakage often resulting from a parting line's irregular surface as found on an O-Ring. Quad-Rings are designed to outperform a standard O-Ring in rotary seal applications. The four-lobed configuration creates a more stable seal avoiding spiral twisting. This allows the use of a more narrow groove width than a standard O-Ring groove, but can also be used in a standard O-Ring groove. Quad-Rings are available in standard O-Ring sizes. |
