Toothed combination gasket

Toothed gasket is a kind of soft metal gasket. It is a metal flat gasket with a good sealing effect. Generally, a precision lathe is used to process a concentric 90-degree angled serrated groove on the two sides of a metal stainless steel flat gasket. Different media, supplemented with flexible graphite, PTFE, asbestos-free board or some other soft metal, pasted on the two sides of the gasket, taking advantage of the tightness of the soft cover layer, the strength of the metal, good elasticity, and both labyrinth teeth The combined gasket can also be used directly without a covering sealing layer, which can also achieve a good sealing effect, but it is easy to cause damage to the surface of the flange in high pressure occasions. Toothed combination gaskets are mainly used for sealing medium and high pressure and high temperature pressure vessels and pipeline flanges.
