This is a fuel injector gasket (seal) for Cummins engines. It seals the joint between the injector and the cylinder head, preventing combustion gas leaks and keeping engine oil and fuel from mixing. Replace this gasket any time the injector is removed or if you notice a compression leak, fuel in the oil, or external wetness around the injector bore.
Confirmed for Cummins B6.7 series per Blaine Brothers listing; always verify the exact engine model and injector bore style.
