Graphoil ring sp.2mm45

This gasket serves as a highly reliable thermal barrier. The specificationrepresents an outer diameter of 45 mm, represents an inner diameter of 20 mm, with a precise thickness of 2 mm (sp. 2mm). Capable of enduring extreme temperatures up to 2000°C without degrading, it is compressed underneath the lip of gold or silver melting crucibles. It ensures an absolute seal against protective gas leaks (such as Argon) during casting, while acting as a shock-absorbing cushion to prevent brittle graphite or ceramic crucibles from cracking when clamped down.
