X-RING / QUAD-RING

X-Rings, also known as Quad-Rings®. X-Rings can be used in a wide variety of static and dynamic sealing applications.

The four-lobed design provides double sealing surface when compared to that of a standard O-Ring. This double sealing action requires lesser squeeze in order to maintain an effective seal. This reduction in squeeze in turn reduces friction and improves the performance life of the seal.

In X-Rings, problems of leakage due to parting line / flash are widely eliminated as the parting lines are between the lobes of the X-Ring and away from the sealing surface. The irregular parting line surface of a regular O-Ring can often cause leakage. X-Rings outperform standard O-Rings especially in rotary seal applications.

The four-lobed design 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. X-Rings are available in standard O-Rings sizes. Please refer to our sizing chart below for approximate dimensions. Please contact us for more information on our X-Rings.
