The double acting GSF Glyd Ring is a combination of a teflon slipper seal and a static 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.
High pressure cylinder piston seals GSF 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.
Seal Ring: PTFE + Bronze O-ring: Nitrile rubber NBR or Fluoro rubber FKM
* Other material combinations can be customized according to working conditions.
