YS F-120 and O-ring question

[jakerresnick]

Hi,

I'm rebuilding my YS F-120 and I'm wondering if anyone know what the red O-rings are made of? is it a special type of rubber and if so, what? I want to try to get new ones at The O-ring store, also if anyone has the sizes that would be awesome.

Thanks
