CF Vacuum Fittings / Flanges

CF Vacuum Fittings / Flanges. One different vacuum fittings type from KF fittings and flanges and ISO fittings and flanges. CF fittings are ideal for ultra-high vacuum environments and are ready to use as received. CF Components, CF Fittings and CF flanges are available in a variety of configurations.

  • Flanges
  • Nipples
  • Elbows
  • Tees
  • Crosses

Features:

  • 1. CF flanges are designed in accordance with ISO 3669 and can be changed upon request.
  • 2. Flange sizes are from CF 16 to CF250.
  • 3. CF flanges are available in both rotatable and non-rotatable models with through holes or tapped holes.
  • 4. Standard materials are 304 and 316L stainless steel.
  • 5. CF products are supplied with a machining finish. Other finishes are also available.
  • 6. Easy assembly or disassembly
  • 7. The system can afford up to Fahrenheit 932 (Celsius 500) for copper gaskets; Fahrenheit 399 (Celsius 204) for Viton gaskets. However, sustained heating above Fahrenheit 302 ( Celsius 150) may result in deterioration of the O-ring.
  • 8. CF flanges are 100 % tested before shipping.
  • 9. Vacuum Range:
    • Copper gasket: >=10-12 Torr
    • Fluorocarbon FKM (Viton) gasket: >=10-8 Torr
  • 10. Seal Temperature Range:
    • Copper: Fahrenheit -325 to 842 (Celsius -200 to 450 )
    • Fluorocarbon FKM (Viton): Fahrenheit -4 to 302 ( Celsius -20 to 150)

Applications:

  • 1. High vacuum and ultra high vacuum
