A "Q"-Rings is a four-lobed seal. The four-lobed design provides twice the sealing surface of a comparable standard O-ring and because of this double-seal action, less squeeze is required to maintain an effective seal. This reduction in squeeze means less friction and therefore, improved seal life. Unlike O-rings, where parting lines are on the sealing surface, Q-ring seals' parting lines lie between the lobes, away from the sealing surface. This design eliminates the problems of leakage often resulting from a parting line's irregular surface. Q-ring seals can be used as compression-type seals in high speed rotary applications, eliminating the need for costlier spring-loaded seals. They offer low friction for long life in hydraulic systems with speeds of up to 900 FPM (4.5 M/Sec.). | |
