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.
