The diameter of the tube is limited by the diameter of the hole that you are trying to blow out. The blower works but the tube is too thin to get a really good blast of air into a 14mm or larger diameter hole .. This is a design fault of the pump. If the nozzle and tube were larger it would do the job much better for that size of hole. If you are using it for holes of a smaller size (say 12mm) then it probably does as good a job as is possible. Otherwise it is well made.
