X-Rings, the seals with the greatest resistance to expansion and pressure

The X-Ring, or Quad-Ring, is an elastomeric sealing part with four contact lips that enables extrusion and pressure to be better withstood. The flexibility of its lips also enables to reduce friction and wear.

This seal also stands out due to the flexibility of the lips, which reduces friction and wear. Whatever the direction of the force (radial or axial), the symmetrical section X-Ring guarantees an excellent seal, even in conditions of low pressure. In the event the pressure of the fluid increases, the elastic activation and rebound increase too. This is due to the fact that the elastomer, on acting like a fluid, transmits the force of the pressure in all directions.

Another of the benefits of X-Rings is that they require less force during start-up, up to 75% compared with other seals. Furthermore, due to their four support points, loss of lubricant is reduced significantly by effectively controlling the thickness of the film.

X-Rings or Quad-Rings, are used in single purpose applications, and, being a “self-energized” element, in static or dynamic.
