Compression Seals; High Voltage Feedthrough Seal - Agilent Technologies 5975C TAD VL MSD Troubleshooting And Maintenance Manual

Compression seals

A compression fitting consists of a threaded fitting on the analyzer chamber
and a threaded collar with a ferrule and O-ring. A cylindrical part fits inside
the collar. Tightening the collar presses the ferrule, compressing the O-ring
around the part. The calibration vials use compression seals.

High voltage feedthrough seal

The high voltage (HED) feedthrough seal is an O-ring that is compressed
against the side plate by a threaded collar.
