EGT Single electrode sealing to 8000VDC

Conax Technologies EGT feedthroughs electrically and/or thermally isolate single electrodes, tubes or temperature sensors for use in vacuum furnaces, liquid level probes, transformers, environmental chambers, power leads and more.

These bare electrical feedthroughs also seal against gases and liquids and resist element movements under pressure. The EGT feedthrough insulators and sealants are provided as a single continuous PTFE piece to accommodate higher voltage/amperage at lower pressures.

Conax EGT feedthrough bodies with NPT threads or SAE threads are constructed from 303SST standard. Weld neck style feedthroughs are constructed from 316LSST standard. Followers for all styles are constructed from 303SST standard. Many optional materials are also available.
