An automobile exhaust gas ceramic catalytic element support device mounts the element in a metal housing and cushions the element from radial shock loads. The device is compressed knitted wire mesh and includes crimped corrugations formed into a cylinder. The cylinder end has a conduit containing a knitted compacted wire mesh rope formed by drawing knitted wire mesh through a die until the formed rope is compacted into a gas seal. The device at the rope end has a radially inwardly extending lip for engaging an end face of the element. The rope may include non-metallic fibers to enhance sealing action of the rope. The device is axially retained by an annular channel in the converter housing with the rope substantially gas sealing the interface region between the ceramic element and the housing.

[ What is claimed is:] [1.] A device for supporting a ceramic catalytic element in a housing of an exhaust gas treatment apparatus, the element having an outer surface and an end face forming a first corner with said outer surface, said gas tending to flow in a first direction in the interface between the housing and element, said device comprising:a mesh member (8, 8') having a side extending in a second direction parallel to said first direction and terminating at opposing ends for supporting at least a portion of said element at said outer surface in juxtaposed relation at the interface between the housing and element outer surface;said mesh member (8, 8') having a conduit formed therein extending transverse said first and second directions; anda fluid sealing elongated member (8, 8') in the conduit and comprising filaments compressed to be substantially fluid impervious for sealing the interface between said housing and said element to preclude said gas flow between the housing and element.
