Installation with angle adaptors

[OlIv0rIolI]

I bought some bitspower 90 degree and 45 degrees angle adaptors. I need it to orient in a certain direction when I screw it on to the radiator, what is the best approach to doing that?
Right now they don't line up the way I want them to.

tighten them more or get a thicker oring

I am afraid I might break something if I tighten it too much. can I use plumbing tapes?

Find out where it lines up when fully tightened.
Make a mark with whatever.
Then make a mark where you want it to be facing. This is an important distance.
Now undo it and stop when the thread ends. Move it round the difference between the two marks (anti clockwise) then retighten. It should be facing the right way now. If it isn't repeat.

You definately want it fully tightened.
