ISO fittings are ideal for high vacuum environments. ISO Components, ISO Fittings and ISO Adapters are available in a variety of configurations.

  • Flanges
  • Nipples
  • Elbows
  • Tees
  • Crosses
  • Clamps and Seals

Features:

  • 1. Flanges are designed according to ISO specification and can be changed upon request.
  • 2. Flange sizes are from ISO 63 to ISO 160. Special sizes upon request.
  • 3. Vacuum Range: ≥10-8 Torr
  • 4. Standard materials are 304 and 316L stainless steel.
  • 5. Tube sizes are from 2-1/2" to 6"
  • 6. The ISO flange system consists of two sexless flanges, an O-ring supported by a center ring and a range of clamps.
  • 7. The system can afford up to 400℉ (200℃). However, sustained heating above 302℉ (150℃) may result in deterioration of the O-ring.
  • 8. ISO products are supplied with a machining finish. Other finishes are also available.
  • 9. Flanges and seals are reusable.
  • 10. Quick assembly and disassembly.
  • 11. ISO flanges are 100% tested before shipping.
  • 12. Seal Temperature Range:
    • Fluorocarbon FKM (Viton): -5℃~204℃ (23℉ -399℉)
    • Silicon: -50℃~180℃ (-58℉ 〜356℉)
    • Buna-N (NBR): -25℃~121℃ (-13℉~250℉)

Applications:

  • 1. High Vacuum
  • 2. Roughing line
  • 3. Vacuum systems, which require cleaning and modified frequently.
  • 4. Experimental system in research laboratories
