The double acting SPGO Glyd-Ring is a combination of a slipper seal and an energizing O-Ring. It is produced with an interference fit which together with the squeeze of the O-Ring ensures a good sealing effect even at low pressure. At higher system pressures, the O-Ring is energized by the fluid, pushing the Glyd-Ring against the sealing face with increased force.
   SPGO works perfectly as double acting Piston seals of hydraulic components such as injection molding machines, machine tools, presses, excavators, forklifts & handling machinery, agriculture equipment, valves for hydraulic & pneumatic circuits and so on.
   
Advantages
- High abrasion resistance
- No stick-slip effect when starting for smooth operation
- Minimum static and dynamic friction coefficient for a minimum energy loss and operating temperature
- No adhesive effect to the mating surface during long period of inactivity or storage
- Easy installation.
