Accofluor Spring Activated Lip Seals

611 (single acting, internal sealing)

Utilizing a strong helically wound spring in combination with a PTFE seal jacket will ensure a good static seal ability and seal ability in both vacuum and cryogenic applications.
The helically wound spring has the benefit of exerting a high spring force at low compression, compared to a seal energized by a V-spring.



  • Very high chemical resistance, compared to similar seals using rubber O-rings
  • Long shelf life
  • Resistant to wear and tear



  • Operation pressure: Up to 85 MPa (850 bar)
  • Velocity: Only for static applications
  • Temperature: -130°C to 260°C
