What Are Bulkhead Feedthroughs?
Hermetic bulkhead feedthroughs are specialized sealing components that permit electrical conductors to pass through pressure boundaries while maintaining an absolute airtight separation between two environments. These components are essential for systems where internal integrity must not be compromised—such as vacuum chambers, propulsion systems, laboratory reactors, marine equipment, and industrial process vessels.
How Bulkhead Feedthroughs Maintain Integrity
Bulkhead feedthroughs must withstand intense mechanical stress, extreme temperatures, pressure cycling, chemicals, radiation, and vibration. Complete Hermetics engineers these feedthroughs using robust glass-to-metal and ceramic-to-metal sealing technologies that ensure leak rates as low as 1×10-8 cc/sec. These seals resist cracking, corrosion, and long-term fatigue.
Configuration & Mounting Options
Vacuum, electric, glass, and ceramic feedthroughs—terms often used interchangeably—serve the essential function of carrying electrical current into or out of a hermetic or vacuum system while maintaining an airtight seal. Complete Hermetics designs and manufactures custom glass-to-metal and ceramic-to-metal feedthroughs engineered to prevent gas transmission through pressure barriers.
The company also produces multi-pin hermetic feedthroughs and bulkhead electrical feedthroughs, which route multiple electrical paths through a single flange-mounted bulkhead. Available in laser-weld or solder-in configurations, these feedthroughs are built for extreme environments. They are used in submersible pumps, downhole drilling tools, exploration devices, implantable medical systems, and cryogenic surgical probes, where long-term electrical continuity and hermetic integrity are essential.
Industry Applications
Bulkhead feedthroughs are widely used in:
- Aerospace propulsion and environmental testing
- Subsea robotics & marine exploration vessels
- Cleanroom vacuum chambers & semiconductor tools
- High-pressure reactors and cryogenic systems
- Defense-grade electronics and hardened enclosures
Material Strength & Long-Term Reliability
Using premium alloys such as titanium, Inconel, Kovar, and stainless steel, Complete Hermetics ensures mechanical stability under prolonged operational stress. Ceramic insulators and precision plating improve voltage tolerance and corrosion resistance.
