BAFFLE SEAL B/U WASHER GB-A4
Theyre round and fit the rivets perfectly!
These are washers, not a great deal to say. The provider is Aircraft Spruce and they have always been spot on with their product availability and speed of processing for shipment.
This is an excellent general purpose Back-up washer. It is thick wall and Larger that the other options that I found on the Aircraft Spruce web site.
Worked perfectly for my baffle seal replacement.
