MIL-SPEC Hermetic Connectors

High-Performance Hermetic Connectors for Harsh Environments

Posted by admin on

Why Hermetic Connectors Matter

Hermetic connectors are vital in protecting electrical and electronic systems from gases, liquids, and extreme temperature swings. Used in aerospace, energy, medical, and industrial equipment, they guarantee reliability when standard connectors would fail. Their sealed construction maintains full electrical functionality in high-pressure and high-vibration environments.

Complete Hermetics Connector Solutions

Complete Hermetics manufactures both glass-sealed and ceramic-sealed hermetic connectors, available in circle, rectangular, and MIL-Spec configurations. Whether for signal integrity, high-power transfer, or data communication, each connector is custom-built to maintain absolute hermeticity and electrical stability.

Engineered Materials for Strength and Weight Reduction

Durability and efficiency meet in every design. Traditional Kovar and stainless-steel connectors are ideal for high-temperature and structural applications, while aluminum and titanium hermetic connectors provide lightweight alternatives for aerospace and defense systems. Each connector undergoes rigorous testing for vibration resistance, thermal shock, and leakage.

MIL-Spec and Custom Options

Complete Hermetics meets or exceeds MIL-DTL-38999, MIL-C-5015, and MIL-C-26482 standards, producing MIL-Spec hermetic connectors trusted by military and aerospace manufacturers worldwide. For legacy or obsolete systems, the company also provides custom-engineered connectors tailored to match older designs while meeting modern performance demands.

Applications Include:

  • Aerospace avionics and propulsion systems
  • Medical diagnostic and monitoring equipment
  • Automotive control and sensing systems
  • Power and communications systems in extreme conditions
