NH220 Exhaust Pipe Ring Seal


Recommended Posts

Anyone have a source for this ring seal for a NH220? It has a 4” ID and round, before it’s compressed into the flange. I’m not having any luck sourcing it through Cummins or my usual go to’s.

I turned one out on a lathe from a brass sheet many years ago and it's never leaked. That however was on my RD-450 engine in a R-190 IH truck which used the same setup. I couldn't find the original type ring seal neither and that was back in the early 90's.
