Purge air line connection to the X-manifold
The connection of the X-manifold purge line to the main purge tubing system in the LVEA was finished today:

- A 20' long tube was re-used from the H2 system leftover tubes after it was proven to be clean, to lengthen the X-manifold purge line
- In the Y-manifold line, a tee was moved closer to the X-manifold, which was used for the connection
- A U-shaped H2 leftover tubing was reused as a connection element over the other tubings and conduits
- 2 more corner pieces, a straight tube, and a bellows were purchased to complete the connection

This work still needed to be done after the decommissioning of the H2 system, as without this, the X-manifold could not be purged. This line is also essential for the regeneration of CP2 in the future.

It was nice work from the vacuum team, the whole thing was done within 2 maintenance periods.
