Semi-Metallic / Metallic Gaskets
Semi-Metallic and Metallic Gaskets manufactured in a wide range of alloys for the most chemically aggressive applications.
KLINGER Maxiflex spiral wound gaskets can be manufactured from a wide range of metals to resist against chemical attack and temperature related degradation and used in combination with either graphite, PTFE or mica filler in accordance with ASME B16.20. Gaskets are color coded to help expedite the selection and identification of the gaskets. The filler material is indicated with a color stripe on the OD. The color on the entire outer edge of the OD indicates the winding material.
Please note: The temperatures given are for guidance only and do not apply in all fluids. Please contact KLINGER Thermoseal’s customer service department for advice.
KLINGER Maxiflex spiral wound gasket dimensions available in accordance with ASME B16.20 used with ASME B16.5 or ASME B16.47 flanges. DIN, BS10, and JIS standards are available upon request.
Custom special gaskets are also available upon request.
