[Looking4] Pro-Craft wax injector manual & parts

Hello, I’ve been lurking for a while and this is my first time
posting (please be nice!)

I am hoping someone could point me in the right direction. I recently
acquired a Pro-Craft Wax Injector. The seal between the pot and the
lid seems to leak air when it’s being pressurized. I was hoping I
could find a replacement seal and maybe a manual. I did a google
search, looking for company website or info and I cannot find
anything.

Any ideas?
Thanks!
Matt
