Specification of SPIRAL WOUND GASKET VALQUA 8590TN
NONASUPER gaskets are manufactured by winding metal strips (SUS304) around the periphery of basic 3.2 mm thick
spiral wound gaskets. The lap wound section of this metal strips around the periphery facilitates centering at the time
of gasket installation, and also enhances the strength of the gasket’s main body. Provided with better sealing
performance than conventional Compressed Asbestos Fiber Sheets, these NONASUPER gaskets can be used with the
same level of tightening force as that of Compressed Asbestos Fiber Sheets.
