Description
        General 
X-Rings or Quad Rings are used in widely differing technical areas, for instance as 
individual sealing elements in pneumatics and hydraulics, and as preload elements for 
seals and wipers. Quad Rings are double acting, activated by the systempressure. The 
sealingeffect is generated by axial or radial preload. The preload of the Quad Ring is 
superposed by the hydraulic pressure, thus assuring the overall sealing pressure. 
Features 
	- Better pressure distribution compared to O-Rings. 
- Used for special dimensioned grooves. 
- Sealing over a wide range of pressures, temperatures and tolerances. 
- Wide application ranges. 
- Simple mounting. 
- Compact and simple grooves. 
- Easy and cost saving constructions possible. 
- Additional grooves on face and cut-off side in order to improve elasticity (special tools 
required) 
Application 
Static sealing (e.g. flanges and threaded joints), rotation and linear movement 
applications with minor loads and small groove dimensions, additional sealing element in 
PTFE seals (PS08C, PS08D). 
Installation 
Snap-in installation
