Wastegate Gasket

Looking for the round asbestos-looking gasket between the lower iron part of the wastegate and the upper aluminum can (or, reasonable alternative). I was originally thinking heat insulation was the primary purpose for the part, but then realized a boost/vacuum leak could also result from this gasket failing.

How hot do you think the top of the WG gets? I am looking at different materials, one being teflon, which is supposed to be good to 500°.
