Sale booked their place in the final of the European Challenge Cup after a comprehensive win at Edgeley Park.
They held a seven-point lead from the first-leg and Chris Jones and Jason White were in top form in the pack.
Bryan Redpath found Charlie Hodgson who skipped past two challenges to score in the corner after 28 minutes.
Leading by 22 points at half-time, Sale made sure with two Mark Cueto tries in the first nine minutes after the break, and he completed his hat-trick late on.
