Sealrite Expanded Pure Graphite (388 Shim & 488 Tanged)
Pure expanded mineral graphite products provide an excellent gasket material for high temperature, high-pressure applications or for applications where the gasket width is relatively narrow. Additionally, the material is resistant to most organic and inorganic acids and is suitable to seal a very wide range of media. It is also almost completely impermeable to gases and fluids and is commonly used in very demanding application where low emission is paramount. The material has no ageing or embrittlement problems common with elastomeric based materials and displays long-term stability of compressibility and recovery over a wide temperature range. Graphite, however, is not suitable for use with very strong oxidising compounds like highly concentrated nitric acid or chromic acid.
Sealrite expanded graphite sheets are made from pure mineral graphite and formed into sheets through a laminar process. Especially used for gaskets for flanges and connections in demanding applications or as an asbestos gasket substitute.
Style 388: Expanded mineral graphite with steel foil sheet reinforcement. The steel foil insertion also allows for better handling and higher operating pressure.
Style 488: Expanded mineral graphite with tanged stainless steel 316 reinforcement.
Stainless Steel 316 sheet allows the material to achieve substantially higher dynamic loading giving it a high blow out resistance and mechanical strength. The insertion also allows for better handling.
