X-Rings (Quad Rings) Description
X-Rings (also known as Quad Rings) have a sealing function doubling that of an o-ring, and can be used in a numerous static and dynamic sealing applications.
Compared to a standard o-ring, the four-lobed Quad Ring profile maintains twice the sealing surface. The double-seal action requires less squeeze to maintain an effective seal function. With a reduction in squeeze, this yields lower friction and prolonged seal life.
To prevent leakage, which typically results from a parting line’s irregular surface on an o-ring, the parting lines on an X-Ring are between the lobes, and away from the sealing surface.
X-Rings are also made to surpass the performance of a standard o-ring in rotary seal applications. The four-lobed design produces a more secure seal to counteract spiral twisting. This allows the use of a narrower groove width than a standard o-ring groove, but can also be used in a standard o-ring groove.
