To install the PEEK tubing in the column outlet:
1. Insert the PEEK tubing into the high-temperature outlet fitting until it
stops.
2. Holding the PEEK tubing, thread the high-temperature outlet fitting
into the column outlet until it is finger-tight.

high-temperature outlet fitting wrench to give the outlet fitting 1/4-turn.
4. Carefully route the PEEK tubing through the column compartment.
Caution: To avoid damaging the tubing, use only your fingers to
tighten the fittings.
Caution: To avoid bandspreading, ensure that the tubing is fully
bottomed in the fitting hole before tightening it.

it with the outlet fitting wrench.
