What High Performance Electrode Gland do Pyrosales provide?

Pyrosales distribute Conax fittings and glands, we have found that the quality of Conax products have the standards which our clients expect from us.  A high-performance electrode gland with Conax1 Imagesingle PEEK™ Insulator (up to 8,000 volts) 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 electrodes (also known as conductor) movement under pressure. The high-performance electrode gland HEGPK 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.

Picture3 1 ImageThe HEGPK gland provide several distinct advantages over Conax EGT Gland:

  • HEGPK glands have higher pressure ratings at room temperature (typically more than 250%), as compared to Conax EGT gland.
  • HEGPK glands also have improved sealing performance at elevated temperatures, as compared to EGT gland.

HEGPK gland bodies with NPT threads or SAE threads 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.

Picture4 ImageConductors are available in Copper, Nickel and 303SST. Use of Nickel rather than Cooper is recommended in oxidizing atmospheres. Custom conductors, such as nickel-plated cooper, are also available.

  • Temperature Range: 0°F to 480°F
  • Pressure Range: Vacuum to 7,700 PSIG (531 bar) – see Pressure Ratings Chart
  • Voltage 8000 VDC
  • Amperage to 200 amps
  • Supplied with or without conductor


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 rating. 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. (a lubrication kit can be purchased).
