Streamline valve seat (Part# 19060)

Hi Everyone - What's the (or your) best method to remove the valve seat from the Streamline (or Dreamline, since it's seems to be using the same valve seat) without damaging it? If possible, could you show a picture of the tool that you use to extract it from the action?

Not something I have to do now. But I'm getting ready for the day I'll have to disassemble it to replace its o-ring...

Thanks !
