"QuanSeal" piston and rod seals are used in hydraulic and pneumatic systems.
Applications:
1) Machine tools
2) Presses
3) Injection moulding machines
4) Forklifts and handling machinery
Operating conditions:
1) Pressure: 0-80MPa
2) Speed: 0-15m/s
3) Temperature range: -80 ~ +250oC
Media: mineral oil based hydraulic fluids, barely flammable hydraulic fluids, environmentally safe hydraulic fluids, water, air and others, depending on the O-ring material compatibility.

This seal is a combination of a PTFE slip ring and an energizing O-ring. It is produced with an interference fit, which together with the squeeze of O-ring ensures a good sealing effect even at low pressure. At higher system pressures, the O-ring is energized by fluid, pushing the slip ring against sealing face with increased force.
Advantages:
1) Lubrication not required
2) No stick-slip effect when starting for smooth operation
3) High wear resistant property ensures long service life
4) Installation grooves according to ISO7425/1, and ISO7425/2 standards
5) No adhesive effect to the mating surface during long period of inactivity or storage
