Here are 2 more ideas:

Install the tube. Use a center punch on the plate holding the
tube, punching a series of dents around the tube. This should
swage the plate material tight to the tube. I would still add the
Loctite.

Does the problem lend itself to installing the tube and driving a
tapered pin/swage tool inside the pipe to swell it outward to the
plate? This could perhaps be done to the tube before assembly,
but maintaining tolerances would be tricky.

Perhaps a combination of both.

Hi. I have an aluminum piece with a hole. There was a tube
pressed into
that hole, but I pressed it out and want to install a different
tube. The
inner diameter of the hole is slightly larger than the new tube
that I want
to press fit into the hole. The new tube can be inserted into
the hole
without a press fit, but it does not rattle around. This is not
a tight
enough fit. It has to be a press fit. I am hoping there is a
tool to
reduce the inner diameter of the aluminum hole so that the new
tube is a
tighter fit. From searching around, it seems that I may need a
knurling
tool. I have a 20 ton shop press, and I am hoping to find
something that I
can press through the hole to make it a smaller hole, causing a
press fit
for the new tube and aluminum piece.

Does anyone have any suggestions on what to do?
