HAPSITE Smart Operating Manual
2.10.3.1 VX-G Conversion Tube Installation
1 The HAPSITE probe has a 3/16" Swagelok® nut installed at the end of the
probe. Inside this nut is a two piece ferrule set consisting of a front and back
ferrule. These must be in place and in the proper orientation to create a leak
free seal. The back ferrule goes into the nut first, followed by the front ferrule
(cone facing forward). See Figure 2-52.
Figure 2-52 Ferrule Location
NOTE: If the nut on the HAPSITE probe is in place, the nut does not need to
be removed. The VX-G conversion tube can be slid inside the nut
opening using the following procedure. If the nut is removed to check
the ferrules, make sure the ferrules are not dropped. Ferrule placement
is critical to insure a leak-free fit around the VX-G conversion tube.
2 Loosen the Swagelok nut on the end of the probe approximately 1/4 to 1/2 turn.
See Figure 2-53.
