Using a bellows design to provide a hermetic seal, the rotary feedthrough provides for rotary motion through a pressure boundary with zero leakage. This is suitable for use with gasses, liquids or vapor.
The bellows construction provides leak tightness to 1 × 10-9 std cc/sec He. With no elastomers, the all welded metal construction allows for operation at -40°F to 300°F. The rotary feedthrough is virtually friction free providing smooth and clean operation
