O-ring size

[Forrest r]

Noob here saying hello & asking a question.

What size are the rubber O-rings that are on the top portion of the RCBS & Lyman sizing dies?

Take a die into a local hardware store. I found Lyman sizer and pressure nut O-rings in the plumbing department.

I asked the same question a couple of weeks ago. Ace hardware STK NO 35768B; #54 O-ring; 11/16x9/16x1/16. It's packaged by Danco, Inc (but of course, made in Taiwan). If there's not an Ace near you, look for a Danco with the same numbers, but other than the dimensions, I don't know which of the numbers are industry standard and which are Ace numbers.
