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® 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® seal uses a narrower groove than a comparable O-Ring seal
Because less squeeze means less friction with the four lobe design, seals last longer
This means equipment in which the Quad-Ring® seal is installed will operate longer and require less maintenance
Unlike O-Rings, where partitioning lines are on the sealing surface, Quad-Rings® seal's 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
