The Metal Tech Hi-Tex series features our specially-designed starburst core tang technology. This robust metal core, available in carbon or stainless steel, provides optimum strength for the laminate in the most demanding applications. The starburst pattern provides 3-4 contact points around the tang and a columnar shape, providing excellent load retention and crush resistance. This technology is best used for high temperature or high load applications such as engine exhaust systems, where sufficient flange loading is available and load retention is required. Generally, the grades in this series are designed for applications such as exhaust manifolds, turbocharger applications, exhaust system gaskets, head gaskets, general industrial flange applications, etc.
