Quad Rings have an x-shaped profile and are also called X-rings or Q-rings. Quad Rings are four-lipped seals with a specially developed sealing profile.
The four-lobed design not only provides twice the sealing surface of regular O-rings or square cut rings, but also lower friction and resists spiral twist.
Quad Rings are vulcanized as a continuous ring, and when squeezed upon installation, seals with the four small contact surfaced on the top and bottom. A lubricant reservoir is formed between the sealing lips that improves performance at start-up.
Quad Ring dimensions are specified with the inside diameter and the cross-section, and are supplied to the American Standard AS-568A and are completely interchangeable with O-rings in these sizes.
They are available in Buna, FKM, and other compounds in standard or metric.
