High Performance Electrode Sealed Feedthrough0 pages

"Example : RS-HEGPK-125 Accessories The replaceable single piece insulator/sealant permits 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.

nnLike 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 PEEKٙ, which is recognized as one of the highest performing engineered thermoplastic materials currently available. The HEGPK Glands provide several distinct advantages over Conaxs EGT Gland:HEGPK Glands have higher pressure ratings at room temperature (typically in excess of 250%), as compared to ConaxҒs 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.
