Maybe what would benefit your assembly operation the most is a

You're right, the tube has up to 5 brushes and 2 plates separated by
elastomer spacers. the stack of parts is almost twice as long as the
tube. The tube already has a flaring operation on one end and is then
forced through the stack and pushes a spring-loaded mandrel that the
parts are stacked on out of the way When the mandrel bottoms out the
tube end hits a flare and "grommets" that end.

Any ideas on how to improve it?

Here's the finished product:
