Nothing special about them. They're available at most local hardware stores. Just take your old one with you and get a match. Easy peasy.

you can get some o rings at and store that has a good selection or online.the piston o rings ASE number is 211 or 212 the 211 fits tight and the 212 is a bit larger dia and fit loose.I like the 212 a bit better.It fits tight in the sizer and will not have the slight spin that the 211 has in my sizer. that said the lyman rings are the only ones that fit perfect. But the other are cheeper and do work. the other 2 you might need are a size 21 for the sleal plug on the botoom of the press and size 15 for the sizeing dies.her is the size chart I found http://www.theoringstore.com/index.php?main_page=page_2

I had the ooseing problem with my old gray 450. I set the casting to machine the bore, I also machined the bottom of the casting flat (had to use an epoxy leveler to fill the low spots), I then drilled and tapped three holes in the base to hold the pressure ring in place.

I'm not sure if Lyman sell the square o-rings or not, I bought package of 100 square o-rings from McMaster Carr, PM me if you need one.
