Electrical & Liquid Feedthroughs
Essex Bay Engineering’s electrical feedthroughs are expertly manufactured by Insulator Seal, Essex Bay Engineering’s ceramic-to-metal seal division based in Sarasota, Florida. Using advanced bonding technology, Insulator Seal joins high-purity alumina ceramics with low-expansion metals to create industry-leading hermetic seals that ensure reliable, leak-tight performance in vacuum environments.
These electrical feedthroughs are essential components in nearly all vacuum systems, providing secure pathways for transmitting high current, high voltage, and sensitive instrumentation signals into and out of vacuum chambers without compromising system integrity. The robust ceramic-to-metal construction guarantees durability and stable electrical performance, even under extreme vacuum and thermal conditions.
In addition to electrical feedthroughs, Essex Bay Engineering’s catalog includes non-electrical fluid feedthroughs designed for both conventional fluid transfer and liquid nitrogen cooling applications. These feedthroughs enable efficient, leak-tight fluid transmission in vacuum systems, supporting thermal management and process cooling needs.
Essex Bay Engineering’s feedthrough solutions combine proven materials and advanced manufacturing techniques to deliver dependable performance for research, industrial, and semiconductor vacuum applications.
