MTG2 gaskets?

Does anyone know where I might get a gasket for an MTG2, someone who makes them or failing either any idea what a suitable material might be to make one myself that won’t melt/catch fire?

Hoop makes them from time to time. Perhaps shoot him a PM and see if he can do a run at the moment.
