rk classic.

They are also referred to as size 013, or Dash Number 013...

I bought a pack of 100 from McMaster Carr for $12 plus shipping. I got the Viton o-rings, which are better than Buna rubber o-rings.

I use them for oil drain plug, trans drain plug, and primary drain plug...


Ooops, I see Fireball Jack posted about the size while I was typing...

Those look to be the same O-rings I got a few years ago from McMaster Carr for like $12 plus shipping... Looks to be a good buy/find.... especially if you have Amazon Prime free shipping like I do..

If I didn't already have a pack of 100, and only 3 bikes, I'd buy that in a heartbeat...
