Conax Technologies Model EG (Electrode) Glands are designed to
conduct rated amperage through vessel walls for applications such
as vacuum furnaces, autoclaves, transformers, power supplies and
other vessels requiring a sealed environment. EG glands also
electrically and/or thermally isolate single electrodes, tubes,
temperature sensors and liquid level probes in pressure/vacuum
applications. These bare electrical feedthroughs seal against gases
and liquids and resist element movement under pressure.
EG gland bodies with NPT threads or SAE threads are constructed
from 303SST standard. Weld-neck style glands are constructed from
316LSST. Caps and followers for all styles are constructed from
303SST. Many optional materials are also available. See page 9 for
details. Cap Style A offers a mounting thread only. Cap Style B
provides threading on both ends for attachment to conduit or
terminal heads. Alternative sealant materials are available. Please
consult a Conax Technologies sales engineer for custom needs.

Accessories
The replaceable sealant permits repeated use of the same fitting.
Electrodes can be easily assembled or replaced in the field.
To replace the sealant or element, simply loosen the cap, replace
the necessary items, relubricate and retorque the cap.
Glands are supplied factory lubricated. When reused, the glands
should be relubricated to maintain the published torque and
pressure ratings. If glands are cleaned prior to assembly, they
should be relubricated. On weld mount models, the heat from
the welding process will destroy the lubricant. These models must
