NAPA or Ace o-ring that fits Lyman bullet sizer?

[higgins]

Does anyone have handy a NAPA or Ace (or other widespread hardware store) part no. for an O-ring that will work on a Lyman sizing die? Thanks

I just took a die into the plumbing department of a local hardware store. Found the correct size right away. Same with the pressure nut's O-rings.

I use these (as on the packaging) 11/16x9/16x1/16 #54 O-Ring STK# 35768B From Ace Hardware.
