Precision Associates Incorporated X-Ring Seals

Low Friction Compression Seals – Run Circles Around O-Rings! After years of concentrated research, PAI has perfected synthetic rubber hydraulic and pneumatic seals that are far superior to O-Rings. These packings were designed to overcome the weaknesses of O-Rings – such as high friction, spiral failures and leakage from compression set. PAI manufactures two types of low friction compression seals: • Multiseal® bi-directional lip style seals • X-Ring multidirectional lobed style seals Both styles offer significant advantages over standard O-Rings, making them the choice for any application where you want to achieve a better, high performing seal. What Makes Multiseal® Low Friction Seals and 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 the 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 force 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.
