Is the bush cracked? Common problem if you tighten the tail into the bush before tightening into the radiator .

No fitted a new bush, and it still driped

Iron fittings have a tapered thread.

Brass fittings have a parallel thread.

Normally.

If you are trying to get a parallel fitting into a radiator that had a tapered thread before, you will struggle, can be done with half a role of well fitted hemp!

Personally I would get a new black iron bush

Might not be the bush, have known the item that the bush goes into spliting open a little bit in the commerical world if to much heave hoe being used.

Get a 3/4 taper thread to 1/2 smash on loads if locktight (10 turns) then a finger of jet blue

Still a parallel thread! So won't help.

Merchant should have a 3/4 T thread to 3/4 socket. Run a 3/4 to 1/2 bush then tail. Bit of a monster but if you can't get the above suggestions .
