Buna-N Nitrile (NBR) 70 Duro Quad Lobe O-Ring Cord

Quad X-Ring Cord Buna-N 70 Cord

The four-lobed design with a specially developed sealing profile of these seals provides twice the sealing surface of ordinary O-rings. 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 Rings are available in a wide range of elastomer materials for both standard and special applications. Their dimensions are specified with the inside diameter "d1" and the cross-section "W." Quad Rings are supplied to the American Standard AS-568A and are completely interchangeable with O-rings in these sizes. They can be used in a variety of static and dynamic sealing applications including rotary, reciprocating or oscillating motion.

Features:

  • There are two sealing surfaces to give a positive seal with less friction. Due to an improved pressure profile over Quad 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.
