I'm not entirely sure, but I thought all injectors have copper washers on them. Our old '94 Cummins N-14 has copper washers on them. Something has to seal out cylinder gas/pressure.

Yup everything from a 645 EMD(Electromotive Diesel) to a 1 cylinder (popping johnny) has copper/brass gasketts around the tip and seat into a copper/brass sleave in the head,has something to do with the quick heat transfer properties as well as being rather soft and malable as metals go.
