ISO Vacuum Fittings / Flanges

ISO Vacuum Fittings / Flanges

Wellgreen offers a complete line of ISO Vacuum Fittings / Flanges. One different vacuum fittings type from KF fittings and flanges and CF fittings and flanges. 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. ISO Vacuum Fittings 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): Celsius -5 to 204 (Fahrenheit 23 to 399)
Silicon: Celsius -50 to 180  (Fahrenheit -58 to 356)
Buna-N (NBR): Celsius -25 to 121 (Fahrenheit -13 to 250)

Applications:

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