Suzy I posted this below in response to your request about source for Magefesa parts. I just now saw it while trying to find some old posts. I wasn't sure that you would see it below.
I just now noticed your post. I called 1-888-787-9991, I don't remember who it was for. I found the number in the manual for a Magefesa pressure cooker that I bought on ebay. The number was handwritten in the manual.
