Advantages

  • 35,000 PSI and above: Robust glass-to-metal seals maintain integrity in some of the harshest environments on earth with 35KSI design pressure and 50KSI burst pressure resistance.
  • Superior pressure resistance and insulation resistance under extreme conditions: ≥10GΩ - with our high-temperature sealing glasses, higher IR can be achieved at 260°C  in some circumstances.
  • Extreme temperature resistance: Eternaloc® connectors are designed to withstand temperatures in excess of 260°C.
  • Fully customizable: Single and multi-pin, male/female connections, and custom materials – flexible design and sampling for a variety of applications.
