When the environment will reach the electronics, the connector has to be sealed.
Custom hermetic sealing for virtually any connector. Engineered and tested for harsh-environment service where standard seals fail.
Hermetically sealed connectors are the answer when moisture, vacuum, pressure, or contamination is guaranteed to reach sensitive components over the service life of the system.
Most connectors are designed for controlled environments. When a system operates in vacuum, high pressure, salt spray, or chemical exposure, a standard connector becomes a failure waiting to happen, not because it is a bad connector, but because it was never built for those conditions.
Hermetic sealing is how engineers close that gap. A hermetically sealed connector uses a fused glass-to-metal or ceramic-to-metal barrier that does not degrade, outgas, or permeate the way elastomeric seals eventually will. For aerospace, defense, medical, oil and gas, marine, and deep-sea applications, that barrier is the difference between a connector that survives the service life of the system and one that does not. RHSeals designs custom hermetically sealed connectors and feedthroughs for virtually any connector geometry: D-sub, USB, panel mount, high voltage, multi-pin vacuum, fiber optic, coaxial, and thermocouple feedthroughs.
Key Benefits
What a Hermetically Sealed Connector Gives You
- Permanent, impermeable barrier: glass-to-metal or ceramic-to-metal construction with no elastomers and no degradation over time.
- Helium leak rate of 1×10⁻⁸ std-cc/sec or better, verified on every unit by helium mass spectrometer. Not a sampling check.
- Pressure capability up to 11,000 psi (758 bar), qualified for deep-sea, downhole, and high-pressure industrial service.
- Works across connector types: D-sub, USB, panel mount, high voltage, multi-pin vacuum, fiber optic, coaxial, and thermocouple feedthroughs.
- Built for harsh-environment programs: aerospace, defense, medical, oil and gas, marine, and R&D, including custom prototypes.
