Does anyone use a silicone spray or anything else on the CTIS disconnect prior to reinstalling?

I looked at the lubrication and maintenance manual but didn’t see anything relevant past “make sure it inflates and deflates” (really?)

 

What I found was to use a silicone spray around the CTIS disconnect and seed/reseed multiple times to work it into the o-ring that is there.

Incidentally, attempted this processes this morning and found the passenger side front link is bubbling while engaged. Explains why I’m losing 5-8 psi daily on the front vs nominal loss on the rears.

 

I have never done that.

 

Climate may be relevant?
