NC Conduit
This is the standard Harnessflex conduit which we use most often.
General purpose use with good impact strength and fatigue life, also available pre-slit down its length.
If in doubt start with this conduit.
CPTA Conduit
Lighter weight and more flexible than the standard NC conduit, at the expense of poorer chemical resistance.
