KnitMesh Technologies wire mesh catalytic converter seals & mesh wraps are used to protect the delicate honeycomb ceramic brick within a catalytic converter from shock and vibration damage.
KnitMesh Technologies wire mesh catalytic converter seals are used to protect the delicate honeycomb ceramic brick within a catalytic converter from shock and vibration damage.
Wire mesh catalytic converter seals are manufactured using mesh that is usually compressed in a die to make an even-density, all-metal one-piece end seal ring. They are designed to protect delicate ceramic bricks and intumescent mats from gas erosion and to prevent exhaust gas bypass between the brick and the inner catalytic converter shell. They are also used extensively within diesel particulate filter assemblies.
Assemblies with two seals that fit around either end of the monolith brick, that are joined by connecting mesh, can also be produced. These seals are particularly useful where the converter does not have any other way of keeping seals in position.
KnitMesh Technologies mesh wraps have been designed to protect the fragile ceramic honeycomb brick within a catalytic converter from vibration and shock damage.
Normally constructed from crimped knitted wire mesh, often in conjunction with an integral strip of intumescent mat material, catalytic converter mesh wraps are usually joined to create a one-piece component that is easily fitted over the ceramic brick during the canning process. The tiny springs that are created during mesh knitting cushion the ceramic brick, preventing damage from the most severe vibration a catalytic converter might experience.
Catalytic converter crimped wire mesh wraps are normally manufactured from grade 304, 316, 321, 310 and 310S stainless steel. High nickel content alloys, such as Inconel* 601 are used for high temperature applications, especially when the converter unit is positioned close to the engine manifold.
