O-ring size for rcbs LAMII..?

[DanOH]

Was sizing some bullets and thought the sizer had ran out of lube a little sooner
than it should have.
When I went to add lube there was a good 1 1/2 inch of lube above the plunger.
The O-ring was in shreads up in the lube.
I had been using LARS c-red so I may have started cranking on the handle before
the lube had softened w/heat.
Is the o ring a standard size that I could pick up locally (what size?) or should i get a replacement from RCBS?
thanks
Dan

Most local hardware stores have a o-ring selection. The only way to know is to measure the size you need and look. An o-ring the right diameter must also be of the right thickness also.

Take the plunger with you to Ace and get what fits.

Contact RCBS and ask for more than one replacement... Don't ask how I know...
