Mr. Phil Z.
Thank you very much!
That kind of info is very useful. I did not know of Viton.
http://www.dupontelastomers.com/viton/?id=wikiviton
I figured the Dometic O ring material would be specific for that kind
of application. And assumed the neoprene (or equal) would not be
appropriate. Or safe. Just didn't know of what it was likely made of.
You've helped save me from spending $$ on a fridge upgrade. Of course
if my final Dometic "mods" don't work, I'll be heading to TruckFridge
land soon enough. Still. Would have been a shame to ditch the fridge
over one silly O ring.
Happy BC day to you and the rest of the Canucks on this list!
Neil.
