What Makes X-Ring Seals Better?
  • Twice the Sealing Surface - Multi-lobed design provides more sealing surfaces than standard O-Rings.
  • Prolonged Seal Life – With multiple seal points, less squeeze is required to provide an effective seal. Less friction and wear will increase seal life and lower maintenance costs.
  • Prevents Spiral Failure - The “X” profile creates a stable seal that is more resistant to rolling in a groove than an O-Ring when used in a dynamic application.
  • Reduced Leakage - Parting lines of X-Ring seals are located in the valley between the lobes away from the critical sealing surface.
  • Better Lubricant Retention - Grooves on the inside and outside diameter of these rings retain lubricant thereby lowering friction and extending packing life.
  • Less Force, Better Seal - Lower breakaway forces and reduced operating pressures make them ideal in reciprocating applications.
  • The Right Fit - X-Rings will fit in standard O-Ring grooves for most applications.
