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. 

For over 60 years, Rocket Seals has provided applicant-specific expertise and stocks a full range of Quad Rings and other seals.  Call us at 9800-445-7803.
