Hermetic Electrical and Fiber Optic Bulkhead Connectors and Hermetically Sealed Feedthrough Wire Seals for Low and High Pressure and Vacuum Seal Standard or Custom Designs

All PAVE hermetic seals are both pressure and vacuum rated in either pressure direction. Also, most of our hermetic seal wire or pin connectors are able to be rated and tested to much higher pressures or lower vacuum helium leak rates than what may be shown on the drawings. Copper alloy wires or pins are sealed for the best ampacity.
