Fischer UltiMate Series - Underwater
Extreme applications depend on data reliability, require rugged connectors sealed to IP68/IP69 to protect devices from environmental interference, or hermetic vacuum and pressurized equipment to prevent gas leaks.

The Fischer UltiMate™ Series meet IP68/69 requirements to guarantee safe and efficient operations in:

  • underwater applications involving immersion over long periods
  • oil & gas applications exposed to high pressures, shock and vibration, where sealing needs must be combined with high-strength mechanical design
