MIL-SPEC Hermetic Connectors

What Are Hermetically Sealed Connectors?

Hermetically sealed connectors provide reliable electrical connections while preventing oxygen, moisture, bacteria, and contaminants from entering sealed systems. These connectors are designed for applications where conventional connectors fail due to corrosion, pressure changes, vibration, or temperature extremes.

A One-Stop Hermetic Connector Manufacturer

Complete Hermetics is a one-stop source for glass-sealed hermetic connectors and ceramic-sealed hermetic connectors, offering both electrically hermetic and vacuum-sealed connector solutions. Custom designs are available for virtually any mounting requirement, filling gaps left by conventional connector manufacturers.

MIL-Spec & Custom Connector Solutions

For military and aerospace applications, Complete Hermetics manufactures MIL-Spec hermetic connectors, including MIL-DTL-38999, MIL-C-5015, MIL-C-26482, and MIL-C-26500, as well as custom legacy replacements. Both circular and rectangular connectors are available with configurable contact counts, shell styles, and sealing technologies.

Lightweight Hermetic Connector Options

Weight matters. Titanium hermetic connectors provide exceptional strength-to-weight ratio and high-temperature resistance, while aluminum hermetic connectors offer ultra-lightweight solutions for low-temperature aerospace and military applications.

Environmental Protection and System Safety

Beyond electrical connectivity, hermetically sealed connectors play a vital role in protecting entire systems from environmental exposure. Moisture ingress, oxygen intrusion, and microbial contamination can quickly degrade sensitive electronics or compromise sterile environments in medical applications. Hermetic connectors create a sealed barrier that preserves internal conditions regardless of external pressure, humidity, or chemical exposure. This level of protection improves overall system safety, reduces maintenance requirements, and supports regulatory compliance in aerospace, medical, and defense industries where reliability and cleanliness standards are exceptionally strict.

Industries Served

Hermetically sealed connectors are used in submarines, offshore oil rigs, vacuum chambers, laboratory equipment, medical devices, and commercial and military aircraft, where reliability is critical.
