4. Tighten the nut in the port until it is finger tight.
5. Carefully turn the nut an additional 1/4 turn (90°) past the point at which the ferrule
starts to grab the sleeve.
Tip: Dionex cannot provide a torque specification because the force
required to tighten the nut can vary due to the friction between nut
and the thread, as well as the composition and wall thickness of the
component to be connected.
6. Remove the preassembled fitting from the tool and inspect the fitting. When you
gently pull the ferrule, you should not be able to move the ferrule on the sleeve. If the
ferrule sleeve moves laterally (
→
Fig. 6), re-insert the fitting all the way into the
preassembly tool and tighten it an additional 1/8 turn past finger-tight.

7. Remove and re-inspect the fitting. Repeat the previous step if necessary.
8. Insert the column (or the fused silica capillary) all the way through the sleeve until it
extends the sleeve (
→
Fig. 7).
