ABSTRACT:
A fire ring assembly includes a unitary fire ring having a plurality of concentrically positioned body portions, each integrally joined to a radially adjacent portion by a radially extending bridge. Each body portion defines a pair of axially aligned, parallel load-bearing surfaces. In a preferred embodiment, at least one of the body portions accommodates a greater compression load per unit of axial distortion. The bridge includes an axially stepped annulus having a greater axial thickness immediately adjacent the body portion affording the greater compression load capacity.
