NOTE: If the nut is removed, ensure that the ferrules are not dropped. It is critical
that both ferrules are in place and in proper orientation to ensure a
leak-free fit around the VX-G conversion tube. See Figure 3-62.
If the nut and ferrules on the HAPSITE probe are in place, they do not need to be
removed. The VX-G conversion tube can be inserted into the nut opening using the
following procedure:
1 Loosen the Swagelok nut on the end of the probe approximately 1/4 to 1/2 turn.
See Figure 3-63.
2 Insert the VX-G conversion tube into the Swagelok nut. Ensure the tube is
firmly seated into the front ferrule. This positions the nut approximately 1/2 in.
from the end of the tube inserted in the probe and 1 inch from the sampling end
of the tube. See Figure 3-63.
