Thermoseal C-4500 is a compressed fiber material with excellent chemical and sealability characteristics. C-4500 is manufactured from carbon fibers with a Nitrile binder system and is an exceptional gasket material for steam and high temperature applications sealing liquids at temperatures up to 850°F (454°C) and gases and steam at temperatures up to 550°F (287°C). This material is typically used as a gasket or seal for compressors, pipe flanges, manways, pumps and valves in applications that require a high internal pressure gasket material.
Thermoseal C-4500 is available in sheets 60" x 60" square in the following thickness: 1/64", 1/32", 1/16", 3/32" and 1/8". If required, Atlantic Gasket will gladly die-cut or waterjet cut parts to your exact requirements and can ship finished parts the same day if needed.
