  • 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 Fahrenheit 400 ( Celsius 200). However, sustained heating above Fahrenheit 302 (Celsius 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):聽Celsius -5 to 204 (Fahrenheit 23 to 399)
Silicon:聽Celsius -50 to 180聽 (Fahrenheit -58 to 356)
Buna-N (NBR):聽Celsius -25 to 121 (Fahrenheit -13 to 250)

Applications:

1. High Vacuum
2. Roughing line
3. Vacuum systems, which require cleaning and modified frequently.
