These are "short" style 1/16" graphite ferrules designed to fit all inlets and detectors on the Agilent / HP 5890 / 6890 except the MSD. The MSD should be used with standard 1/16" ferrules, preferably made from Vespel®graphite.

Graphite ferrules are made from 100% high-purity graphite with an upper temperature limit of 450° C. Ferrules are precision formed with a flash-free ID and may be reused if not overtightened.

Please note:
0.5mm ID ferrules fit 0.25 to 0.32mm ID capillary columns
0.8mm ID ferrules fit 0.53mm ID capillary columns
