Its because when you push pipe into the fitting the excess flux gets pushed into the pipework system, if you put it onto the pipe you will see the excess seep out externally.I apply it just to the pipe and turn the fittings around on the pipe so it goes smoothly around everything,
The 2 blokes i work with both put it in the fitting and on the pipe, they teach at college NOT to put it in the fitting EVER,
not sure why!
