Hermetic Connectors, Electrical Wire Feedthroughs & Fiber Optic Feedthroughs for Vacuum & Pressure Seals

All PAVE hermetic connectors are both pressure and vacuum rated in either pressure direction for proven highly reliable hermetic seal long-term lifetime use. ISO 9001 quality system. Also, many of our hermetic seal wire or pin connectors are able to be rated and tested to much higher pressures or significantly lower vacuum helium leak rates as low as 4 x 10^-10 cc/sec if an o-ring face seal type design, than what may be shown on the drawings. Copper alloy wires or pins are sealed for the best ampacity.
Turn to PAVE Technology for high-quality, dependable electrical feedthroughs. As an industry leader in the manufacturing of electrical wire and hermetic feedthrough products, we’ve got the equipment you need.
