Any usggestions?
Are you trying to screw them into a tube? Could you instead push them
in and then fill the tube with epoxy or potting compound through a hole
in the side?
Could you make the tube in two short lengths, with a left-hand thread
between them; screw the plug into one part and then screw the socket
into the other while also screwing the two parts of the tube together?
Could you use a split (lengthways) tube, solder the resistor to the plug
and socket, and fit the tube on with epoxy?
Or if it doesn't need to be absolutely rigid, mould some Sugru round the
parts instead of using the tube?
