Complete Hermetics

What Complete Hermetics does

Complete Hermetics is a custom manufacturer of glass-to-metal and ceramic-to-metal hermetic seals, feedthroughs, connectors, headers, packages, and vacuum viewports, founded in 2002 and headquartered in Santa Ana, California. The company operates as a wholly owned subsidiary of Aegis Technology Inc. and serves defense, medical technology, semiconductor, energy/offshore drilling, aerospace, and industrial customers requiring airtight, gas-tight, and moisture-tight electrical interfaces that withstand extreme temperatures (-100°C to 500°C), high pressure (up to 30,000 psi), vacuum, vibration, and corrosive environments. Its core technology is the precision thermal-expansion-matched bonding of glass or ceramic to metals including Kovar, titanium, stainless steel, Inconel, and aluminum, with hermeticity tested to leak rates below 1×10⁻⁹ atm·cc/sec He on demanding product lines.

The product portfolio spans MIL-DTL-38999 circular connectors, custom and standard circular/rectangular hermetic connectors, multi-pin and single-pin feedthroughs, multi-pin/single-pin/TO headers, hermetic microwave/hybrid/power/photonic packages, battery end seals, vacuum viewports, and ceramic-to-metal brazing/soldering services. The company holds ISO 9001 certification, RoHS compliance, and conforms to MIL-STD-883, MIL-STD-1344, MIL-DTL-38999, MIL-PRF-13830, and JEDEC-9C, supporting qualification for mission-critical defense and medical implantable applications. Named customers include Primus Aerospace, St. Jude Medical, and Broadley-James Corporation, reflecting design-in relationships across aerospace and medical device end markets.

Revenue is generated through one-time custom product sales with quote-based pricing, supported by direct sales via phone (714-265-1238), email, and a website quote request system. No channel partners or distributors are used. The go-to-market is enterprise field sales targeting engineering and procurement decision-makers, supplemented by an active blog with educational content on hermetic sealing technologies. The company claims global service capability from its single Santa Ana, CA facility, supporting both prototype and mass-production runs. No revenue, headcount, or external funding data is disclosed, consistent with its status as a privately held subsidiary within Aegis Technology Inc.
