O.S. Engines 21RZ Exhaust Gasket OSM22826140

This is one pair of exhaust adaptor rings. They highly resemble large grommets, as their function is quite similar. These are the newer series of adapter rings that replace the older 2-ring design. All of these do is form a seal for the manifold of rear exhaust engines.
