Dart Big M Aluminum Block Threaded Freeze Plugs
Anyone know what thread these are? Guessing either straight pipe or AN as they use an O-ring.

They are considered an AN ORB (o-ring bung)

I used to get -16 AN plugs to replace those. And even though they use an o-ring use some type of thread sealer on the threads. Usually they're being replaced because the threads corroded...
