Clean off the old silicone and wipe the contact areas with silicone primer (Divex Part No.
SM021).

5. 

Fit a new O-ring (Fig 4.11, Item 3) to the upper penetrator (Fig 4.11, Item 1) and apply a bead
of silicone sealant (Divex Part No. SM006) around the sealing face of the penetrator.

6. 

Re-install the penetrator into the scrubber housing and refit the locknut (Fig 4.11, Item 2)
using the tools described in Step 2 above, and with a moistened finger carefully wipe the
excess silicone sealant smooth before it sets.
