Thanks for the heads up! Yeah I did come across that site. Unfortunately, Buna is a gasket material that doesn’t hold up to higher temperatures and some chemical resistances like Viton does. The gasket I need will be used in a fuel application in a motor. I did cut a sheet of Viton I have but obviously I don’t want to do this if it’s going to hurt the machine and be unsafe.
Dang it, too bad, the Buna stuff sounded promising. It seems there are a lot of folks looking for laser safe gasket material and I’m not seeing a lot of success. Hopefully some of our resident chemist folks pop in to give an answer. Good luck in your search. Hopefully there’s a flourine free Vitron out there some where.
