  • Alloys: X750, 600, Aluminum, Silver, Copper and Nickel
  • On Request: Gold, Tantalum, Hastalloy, Monel, Titanium, etc.

Typical Applications:

  • Chemical delivery canisters / ampoules
  • UHV pump / chamber connections
  • Gate / slit valves
  • Odd shaped chamber ports
  • Standard ISO flanges
  • Quartz windows / ceramic flanges
  • RF waveguide connections
  • Cryogenics / superconducting magnets

Performance Characteristics:

  • Load required to compress approx. 150 lbs/circumferential inch
  • Typical sealing level: Q<10 -6 cc/sec He to 10 -10 cc/sec  He
  • Temperature: -269¼ C to 350¼ C
  • Vacuum: Ultra high vacuum

Additional Information:

  • Sealing level: Q less than or equal to 10-13 cc/sec He
  • Temperature: -458¼ F to 1292¼ F  (-272 ¼ C to 700 ¼ C)

Sealing Concept:

A type of Helicoflex seal, the Helicoflex Delta® uses two small ridges or "Deltas" on the face of the seal.  The load required to reach ultra-low Helium leak rates is reduced by concentrating the seal contact area.
