Separation Rings

Separation Rings

KnitMesh Technologies knitted mesh separation rings have been developed to provide a constant gap between the two ceramic honeycomb bricks in twin-brick catalytic converters.

Using a metallic knitted wire mesh separation ring ensures the gap is consistent and prevents gas erosion of intumescent mats.
Separation rings can be produced in a wide range of materials including 304, 316, 321, 310, and 310S stainless steel. Inconel 601* can be used in high temperature applications.
For better shape definition, a sleeve of knitted wire mesh can also be placed around the outside of the wool packing.
