Some of my pieces are chainmail, which includes at least one design
using rubber rings. Since my original source discontinued them and
another doesn't have the right size, I've found myself on the
industrial sites--where I'm encountering a slew of new acronyms.
I'm looking for -010 black, so that at least is pretty common, but
should I be using EPDM? Viton? Something else?
Supplier recs? http://www.ganoksin.com/gnkurl/ep7zpp
is looking pretty good.
