ISO Claw and Bolt Flanges are designed for large tube diameters from 2½ to 20 inch diameters (63 to 500mm).

Specifications

Atlas aluminum ISO Claw and Bolt flanges are fully compatible with existing third-party ISO flanges and hardware.

Material

Body/Weld Interface: Aluminum 6061-T6

Environmental

  • Vacuum Rated: 1x10-8 Torr
  • Peak Temperature (Intermittent): 200°C
  • Operational Temperature: -20°C to 150°C
