Other Details

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 fiction than an O-ring, but also, due to its square cross section, it resists spiral twist. Quad-Ring® Seals are available in a wide range of elastomeric materials for both standard and special applications. Quad-Ring ® Seals are vulcanized as a continuous ring. Quad-Ring® Seals are supplied to the American Standard AS-568A and are completely interchangeable with O-rings in these sizes. Quad-Rings® Seals are available in all standard O-Ring sizes from 1/32" to 26", as well as custom seals for unique applications.    Manufacturers of Quad rings - provides twice sealing surface, better positive seal, minimum friction, avoids  spiral twists, withstands distortion & extrusion.
 
Features:

• There are two sealing surfaces to give a positive seal with less friction. Due to an improved pressure profile over Quad-Ring© Seal cross-section, a high sealing effect is achieved.
• The recessed mold parting line provides no flash or parting line on the surface of the seal and ensures "zero leakage." What's more, a lubricant reservoir formed between the sealing lips improves performance at start-up.
• The quad cross-section resists spiral twisting and extrusion. Due to its special profile, the seal does not tend to twist in the groove during reciprocating movement.
• Twice the sealing surface means less radial squeeze is needed to create an effective seal resulting in less friction, less wear & and longer service life.
