Baseboard Creaky Noises

Considering the fins on fin tube baseboard are aluminum I don't see a problem.

Sioux Chief, Jones and a few others still manufacture those bushing. BUT they need a 1-3/8" hole for them to fit into.

The one with the two nail "wings may fit in a smaller hole, don't nail these in, let them float with the tube, of course.

Often times a 1" hole is drilled and a 7/8" tube installed in it. Not much expansion room.

The hole needs to be fairly large for baseboard installations and element longer than 8 feet should have an expansion joint. There is lots of movement in copper as it heats and cools.

I agree outdoor reset or constant circ with temperature injection may be the best fix if holes cannot be enlarged.

If it is rubbing on a joist some EPDM foam insulation may help, and lessen the heat loss

Don't see how you can do that and still have optimal heating performance but . . . .

You do this with constant circulation and lower temperatures. It might pop a very little every once in a while, but not on ramp up to 160 or whatever the water set point is then back to ambient again and again and again.

For low budget homeowner fixes:
Try your thought of furniture wax or polish.
If that doesn't work, cut a piece of plastic milk jug - low density polyethylene - or something similar and wedge it through the hole around the pipe.
