GOT-420 Corrugated Metal Gasket is processed by metal flat ring into concentric waveform coil by die-pressing, rolling, or turning techniques, with the surface sticking non-metal as expanded graphite or PTFE. Comparing with 410 Kammprofile gasket , the lining metal can choose multiple thickness, as 3mm, 2mm, 1mm, 0.5mm, etc. and the metal wave distance can be different according to the width difference of the sealing surface, generally be 3mm, 4mm,6mm, etc.
