ORK pioneered the design and production of four-lobed seals with the Quad-Ring® Brand seal design. These seals are used today around the world for a wide variety of static and dynamic sealing applications.
Avoiding Spiral Twist
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 Quad-Ring® Brand seal's four-lobed configuration is designed to withstand the distortion and extrusion often caused by high or pulsating pressure. To accommodate these forces, a Quad-Ring® Brand seal uses a narrower groove than a comparable O-Ring seal.
Longer Seal Life
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.
No Parting Line on Sealing Surface
Unlike O-Rings, where parting lines are on the sealing surface, Quad-Ring® Brand seals' parting lines lie between the lobes, away from the sealing surface. This design eliminates the problems of leakage resulting from a parting line's irregular surface.
