Lobed Ring AS-568 NBR 70A

Quad-Rings™, also called lobed or X-rings, are designed to take the place of a traditional O-ring. To minimize breakaway friction, an O-Ring groove must be wide enough to allow rolling or twisting of the seal. In the long stroke of a reciprocating seal application, this twisting action can strain and eventually tear the rubber, causing a failure mode known as spiral twist. To prevent spiral twist the seal's four-lobed configuration is designed to withstand the distortion and extrusion often caused by high or pulsating pressure. Because less squeeze means less friction with the four-lobe design, seals last longer. Therefore, equipment in which the Quad-Ring® Brand seal is installed will operate longer and require less maintenance.
