User Guide
The design of UltiMetal Plus Flexible Metal ferrules reduces the probability of column
breakage and minimizes the damage to the thread of the corresponding fittings.
Unlike other ferrule designs, a reliable leak-free seal is best made by tightening the
internal nut to a recommended number of degrees, not by applying more force. Applying
excessive force will not provide a better seal. Also, compressing the flexible ferrule less
minimizes damage to fittings.
To swage the ferrule to the column:
a Find your ferrule type in
nut.
b Tighten the internal nut clockwise to the lower end of your ferrule's range.
c Check if the ferrule is gripping the column. If yes, stop. If not, continue to tighten the
internal nut in small 5- to 15-degree increments. Check after each increment to see if
the ferrule is gripping the column. Stop as soon as gripping occurs (see
