Vacuum Pressure Feedthroughs

Vacuum Pressure Feedthroughs

Key Features

  • Vacuum or pressure seal
  • Fiber in penetrating style can be protected in 900?m loose tubing or 3mm OD stainless steel cable
  • Rugged design
  • Compact
  • Low transmission loss (excluding connecter losses)
  • Easy installation


Fiber optic vacuum feedthroughs provide a simple way to use optical fibers with vacuum and pressure chambers. They are available in two versions – a penetrating feedthrough fiber version and a receptacle style version.

Penetrating versions have the fibers directly installed. One or four fiber versions are available. The fibers are installed in the factory. The fibers pass through a soft sealant material which is compressed by the compressive endcap and internal squeezer of the feedthrough.
