Swagelok tube fittings' installation
instructions
1. Insert the tubing into the Swagelok tube
fitting. Tubing should rest firmly on the
shoulder of the fitting. The nut should be
finger tight.
2. Mark the nut at the 6 o'clock position.
3. Hold the fitting body with a backup wrench
and tighten the nut 1¼ turns. Watch the
marking and make one complete turn and
continue to 9 o'clock position.
CAUTION
The DM500 as delivered from the factory has 6 mm Swagelok tube
fittings. If you use ¼" tubing, always use the proper ¼" adapter
fitting (provided). Make sure the adapter is connected the right way.
An incorrectly connected adapter or connecting ¼" tubes straight into
the 6 mm tube fittings may lead to product damage. See Figure 12
and Figure 13 for visual instructions.
