[TR] Stromberg plug o-rings

Can't find my note at the moment, but I'm pretty sure that's not the right
number.  -114 would indicate a 5/8" od, and the bore in the rod is much
smaller than that.

Viton would work I believe; but I used ordinary Buna-N (nitrile rubber) as I
believe that's what the originals were (and what I had on hand).  EPDM/EPR
(Ethylene Propylene whatever) is definitely the wrong thing, IMO, as it has
poor resistance to petroleum oils.

ISTR Mine came from Harbor Freight, in one of these kits
http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=2901

Bought on sale for 1/2 price; figuring that even one O-ring used from it
would pay for the kit.  It's been handy many times since then.  In fact,
just a few days ago, I tried several O-rings from the kit until I found the
one that fit my bearing extractor (holds the tip to the forcing screw).
