Ferrules
Restek offers graphite and VespelYgraphite (60%/40%) ferrules to usewith capillary columns. The graphite ferrules are made
from highly-compressed ribbon that will not crack or split under torque. TheVespel/graphite ferrules are designed to seal easily
with minimal torque, are reusable, and are preferred for vacuum and high pressure uses. Both ferrule types are stable to 400°C.
