I made mistake of greasing an o-ring on my water filter housing with
Vaseline and it expanded too much. I easily shrunk it back with careful
heating with a heat gun.

I tried that once, but no-go.

Sounds like I am going to try it again - with a little more heat and
time.

Worth trying. Worse you could do was have to buy a new gasket. The
o-ring for my unit listed for $11 which I think is outlandish. OEM
suppliers can hose you with parts cost.
