Quad ring seals are four-lipped seals with a specially developed sealing profile that actually provides twice the number of sealing surfaces as an O-ring. The four-lobed design not only provides lower friction than an O-ring, but also, due to its square cross section, it resists spiral twist.
Quad Rings seals are available in a wide range of elastomer materials for both standard and special applications. Quad-Ring seals are vulcanized as a continuous ring. Their dimensions are specified with the inside diameter “d1” and the cross section “W”.
Quad-Rings Seals are available in all standard O-Ring sizes from 1/32” to 26”, as well as custom seals for unique applications.
