AT702, AT703, AT703a: Kammprofile
Composite Gasket is made by soft iron or stainless steel, processed by
mechanical machining, forming a 90-degree concentric ring gear. And some
expanded materials are usually covered.High pressure is achieved under
low preload due to the tooth tip contact when Kammprofile Composite
Gasket is applied in flange,resulting in excellent sealing performance.
Three types of Kammprofile Composite Gaskets,they are:
AT702: Basic type
AT703: With an outer ringtype
AT703a:With a removable outer ringtype
