iirc, been a minute, dont think there was a gasket ( not sure) and it looks like its welded twice there. these are from my cpi's. fattys look completely different. Not much help, been a long time since i repacked, but seems like the pipe continues inside where its full of holes . gonna be hard to repack now. Does the other end have these caps too?
