tight leak off pipes

[jpliddy]

hi all i recently purchased a length of leak off pipe from Brickworks uk , the bore diameter is 3.2 mm which i believe to be correct for the D24 engine injectors
the the pipe is a very good quality but ,
a little tight on the edge that runs onto the injector i have tried and tried , question !. is it safe to try and force the leak off pipes over a couple of degrees
with utmost care ? , to allow the pipe to sit snugly down at the bottom of the leak off pipe , i have replaced these pipe numerous time over the years with a budget range ,so i thought i woud get better quality i also purchased a genuine VW stop end whichich does fit snugly over the leak off pipe it is a thinner gauge too
regards jim
