Reassembling Water Loop

[Corrupt_Liberty]

My graphics card just failed on me and I had to send it in for warranty so obviously my water cooling loop had to come apart.  It has been running flawlessly for about six months now.  When pulling the PETG tubing out of my Bitspower fittings I noticed the o-rings wanting to cling to the tubing.  The o-rings are also very dry.  I was wondering if I should replace the o-rings when I reassemble the loop or maybe put something like vaseline on the o-rings to prevent dry rot.  Just trying to prevent problems before they occur.

If they aren't hard and rigid (Kappa), it should be fine.
