Applications for Vacuum Chambers or Gloveboxes

vacuum feedthroughs

Apex Wire Seal feedthrough or cable pass through feedthroughs are designed to pass cables from atmosphere to high vacuum. Cables can include most types of instrumentation wire or cable. Standard temperature range is from -40F to 200F. Please consult our factory if your specifications are outside this temperature range. Each wire feedthrough has a 12 month warranty.

Custom cables can usually be sealed to provide power, thermocouple or communications to vacuum chambers of glovebox systems. Cables such as USB, Ethernet and many photography cables have been passed through into vacuum or glovebox systems.
