Metal serrated gasket，is processed into concentric grooves on both sides of stainless steel flat gasket by use of precision lathes. Flexible graphite, PTFE, non-asbestos sheets or other soft metals can be pasted on its two sides according to different mediums. It can be also directly used without sealing layer, and achieves a good sealing effect. But it will easily damage the surface of the flange under a high pressure.

Product Applications：

Under the condition of lower pre-tightening force, this gasket is the first choice. The soft sealing layer avoids direct metal-to-metal contact and can be bonded reliably and closely, therefore preventing the metal flange from being damaged even under high load. Serrated compound gasket, the ideal substitute of traditional metal jacketed gasket (MJG), is especially applied in flange joints of heat exchangers, containers and reactive kettles under high temperature, high pressure and alternating working conditions. Pressure range: 64-25Mpa

Optional Materials:

Other metals can be selected as required.
