GOT Kammprofile gasket , generally processed to be concentric groove in the two faces of the stainless steel flat gasket by precise lathes. According to the different medium, w can choose flexible graphite, PTFE, non-asbestos, or other soft metal, to sick to the two faces of the gasket. It can directly be used without sealing layer, and the effect is good. But under the high pressure occasion, it will be easy to do damage to the surface of the flange.
410 basic type Kammprofile gasket
410L Kammprofile gasket with outer ring (integral type)
410LM Kammprofile gasket with outer ring (split type)
Model 410LM split type Metal toothed gasket with outer ring, can choose richer metal, e.g. carbon steel, as the outer ring, and the outer ring thickness can be 1.5mm, more flexible and economic than the integral type 410L, and the lining metal can be repeatedly used.

Product application:
GOT toothed combination gasket is the first choice gasket under relatively low preload power, the soft surface of the sealing layer can avoid the direct touch between metal and metal, which is combined reliably and compactly, to protect the metal flange from damaged, even under extremely high load. The toothed combination gasket is especially suitable for the flange connection in thermal exchanger, container, and reaction vessel under high temperature, high pressure, and the working condition altering occasions. It is an ideal substitution for traditional metal jacketed gasket. Operating pressure range: 6.4~25Mpa
