As far as I could tell, the rubber was holding up well. After being stretched out, it returned to its original shape just fine.

Time to put this "experiment" to an end. I stretched the o-ring out again to see if it had lost any of its elasticity or if it would deform. From what I could tell, the little o-ring was just fine after nearly 30 full days soaking in WD40. > http://img216.imageshack.us/img216/802/hpim1053br6.th.jpg (http://img216.imageshack.us/my.php?image=hpim1053br6.jpg)http://img216.imageshack.us/img216/4880/hpim1054kz9.th.jpg (http://img216.imageshack.us/my.php?image=hpim1054kz9.jpg)http://img216.imageshack.us/img216/273/hpim1055fq5.th.jpg (http://img216.imageshack.us/my.php?image=hpim1055fq5.jpg) > > So if the function of the o-rings in an o-ring chain is to keep water and dirt off the roller pins > and to hold the grease in place, it looks like the o-ring rubber is not affected by WD40 in a way that would inhibit it from doing its job. And, of course, if you're wiping your chain down with a WD40 soaked rag or even spraying the chain directly with WD40, the exposure of the o-rings to WD40 is nowhere near what the o-ring in this little test was exposed to. > > You too can have this kind of fun by devising your own o-ring tests and posting the results online. Now that I think of it, I find myself very curious about the effects of a propane torch flame on o-ring rubber. Would it last a month? >
