What did I do wrong?

Did I get the wrong size? Is there an adjustment that can be made?

 

Are you certain it's not cross-threaded? Could just be optical illusion but i'm not certain it's on straight.

 

Isn't there normally a spacer piece?

 

It is on straight. I checked all three taps and all 5 ferrules. There is not currently a spacer on the black plastic handles.

 

Hey,

Give this a shot - with mine the two crosshatched pieces, the grippy metal parts ( don't know the proper name ) are actually two pieces, the top part is threaded on and it moves so that the handle can be secured without the gap - that worked for me

 

But then there is a gap below.
