Precision, reliability, and compliance with military standards are essential in mission-critical applications. Whether in aerospace, defense, medical, or industrial systems, sensor seals must withstand extreme environmental conditions while ensuring leak-tight performance. That’s why mil-spec type sensor seals play a vital role in safeguarding electrical connections, data transmission, and operational stability in high-stakes environments.
At Hermetic Seal Technology, we specialize in designing and manufacturing mil-spec type sensor seals that not only meet but exceed military and federal compliance requirements. Engineered for performance, our sensor seals provide hermetic integrity, electrical insulation, and environmental protection across a range of demanding applications.
Unmatched Performance in Extreme Conditions
A standard seal is not enough for critical operations that face high pressures, extreme temperatures, and corrosive environments. Our sensor seals are built with advanced materials and precision-engineered sealing technology to ensure they provide leak-tight integrity, electrical insulation, and mechanical durability. This protects against moisture, gases, contaminants, and voltage fluctuations that could compromise system performance.
Customizable Solutions for Every Requirement
Each application has unique requirements, which is why our sensor seals offer extensive customization options.
Coupling and Connector Types
We provide a wide range of connection options, including bayonet coupling for a quick and secure locking mechanism, push or pull connectors for fast installation, threaded seals for high-pressure environments, and custom coupling configurations designed to integrate seamlessly into proprietary systems.
Material Selection for Maximum Performance
The right material is crucial for ensuring durability and long-term reliability. We offer shell materials such as stainless steel, plated mild steel, and Inconel, along with high-purity glass insulators made from borosilicate, barium alkali, and other specialized formulations. For contact materials, we use alloy 52, molybdenum, platinum-iridium, and other high-performance metals to ensure optimal electrical properties.
Plating Options for Enhanced Durability
To provide added protection and conductivity, we offer gold plating for corrosion resistance and superior conductivity, nickel plating to improve mechanical durability, and silver plating for enhanced thermal and electrical conductivity.
Precision Manufacturing and Rigorous Testing
Our production capabilities range from prototype development to high-volume manufacturing. We adhere to strict quality control protocols to ensure every sensor seal meets military and federal specifications.
Key Testing and Quality Assurance Processes
Every seal undergoes 100 percent leak testing with a helium leak rate of less than 1×10⁻⁸ cc/sec. Additional testing includes high-voltage breakdown testing to ensure electrical insulation integrity, electrochemical corrosion testing to validate resistance to harsh environments, and salt spray corrosion testing to simulate real-world exposure.
