High Performance Electrode Gland
With Single PEEK™ Insulator (up to 8,000 Volts)
Like the EGT Gland, Conax Technologies HEGPK
Glands 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 electrode (also known as
conductor) movement under pressure. The HEGPK
Gland differs from the EGT gland in that the single piece
insulator/sealant is manufactured from PEEK™, which is
recognized as one of the highest performing engineered
thermoplastic materials currently available.
The HEGPK Glands provide several distinct advantages
over Conax’s EGT Gland:
•t
•t
HEGPK Glands have higher pressure ratings at
room temperature (typically in excess of 250%),
as compared to Conax’s EGT Gland.
HEGPK Glands also have improved sealing
performance at elevated temperatures, as
compared to EGT glands.
HEGPK gland bodies with NPT threads or SAE threads
are constructed from 303SST standard. Weld-neck style
glands are constructed from 316SST standard. Caps
and followers for all styles are constructed from 303SST
standard. Many optional materials are also available.
Cap Style A offers a process mounting thread only. Cap
Style B provides threading on both ends for attachment
to conduit or terminal heads. Please consult a Conax
Technologies sales engineer for custom needs.
Conductors are available in Copper, Nickel and 303SST. Use
of Nickel rather than Copper is recommended in oxidizing
atmospheres. Custom conductors, such as nickel-plated
copper, are also available. Please consult factory.

Accessories
The replaceable single piece insulator/sealant permits
repeated use of the same fitting. Conductors can be easily
assembled or replaced in the field. To replace the insulator/
sealant or conductor, simply loosen the cap, replace
necessary items, relubricate and retorque the cap.
Glands are supplied factory lubricated. When reused, the
glands should be relubricated to maintain the published
pressure ratings. If glands are cleaned prior to assembly, they
should be relubricated. On weld models, the heat from the
welding process may destroy the lubricant. These models
must also be cleaned and relubricated prior to use. See page
103 in Catalog 5001C for information on our lubrication kit.
