710D (single acting, durable lip)

AF-710D is our standard and best-selling ASL-seal.
It provides a tight seal whether the system is in motion or stationary. The fact that the seal seal is activated by a metal spring, rather than the typical rubber O-ring, gives it a range of sometimes crucial advantages:

• No deformation-set
• Expanded chemical compatibility
• Tolerates a much larger temperature span
• Very low friction coefficient, even compared to other PTFE seals, due to having a tiny contact area with the counter surface.

Advantages:

• The dynamic lip is thick, to ensure a long lifespan for the seal
• Long shelf life

Limitations:

• Operation pressure: Up to 45 MPa (450 bar)
• Velocity: 15 m/s
• Temperature: -70°C to 260°C
