3-1/2" Gasket Set Silicone Rubber & Graphite for Vacuum Casting Perforated Flask by JTS

A set of 3-1/2" gaskets... - High Grade Silicone and Graphite High Temperature gaskets. Gaskets are used together to provide the best seal during vacuum casting to seal perforated flask ring and casting chamber. - The Silicon acts as a sealing layer while the graphite placed on top of the silicone, protecting and prolonging the silicone seal - from the high flask temperature. - The combination of the 2 types of gaskets provide a very good seal, allowing the vacuum to fully pull the molten metal into the flask. - These gaskets are die cut, have a thickness of 1/8" for the Silicone and 1/16" for the Graphite. Gaskets come in various diameters to work with individual flask OD sizes, visit our store.
