Hermetic Seals and Feedthroughs for Reliable Protection

Why Hermetic Seals Are Important

Hermetic seals protect sensitive electronics from moisture, pressure, and gas leaks. In industries such as aerospace, defense, automotive, and medical, glass-to-metal seals and ceramic-to-metal seals provide airtight reliability where failure is not an option.

Complete Hermetics Seal Solutions

Complete Hermetics is a custom hermetic seal manufacturer specializing in glass-to-metal feedthroughs and ceramic-to-metal feedthroughs. Their engineers create custom prototypes and production-ready components to fit unique requirements across multiple industries.

Applications include:

  • Aerospace and defense electronics
  • High-voltage and vacuum systems
  • Medical devices, batteries, and sensors

Glass-to-Metal Seals

Glass is heated to a molten state and bonded to metal, creating a strong hermetic seal. These seals handle temperature changes, pressure variations, and corrosion resistance. Glass-to-metal feedthroughs are also cost-effective and versatile compared to ceramic alternatives. Options include compression seals for extreme pressure (up to 14,000 PSI) and matched seals for high thermal and mechanical shock resistance.

Ceramic-to-Metal Seals

For high-temperature, high-voltage, or harsh environments, ceramic-to-metal seals offer superior durability. While more labor-intensive to produce, they provide long-lasting performance in vacuum feedthroughs and electrical sealing applications.

Plating and Material Options

Complete Hermetics offers plating choices such as gold, silver, nickel, and tin to improve corrosion resistance and soldering capabilities. Materials include stainless steel, Inconel, Kovar, copper alloys, and high-performance ceramics, depending on application requirements.
