Insert the hard sponge ball behind the last concrete charge, then run water or air to push it through the pipeline. A 60 mm ball is commonly selected for smaller-diameter pump lines; the ball should be slightly larger than the pipe inner diameter for effective cleaning.
Hard balls clean more aggressively but create higher back-pressure. Confirm pipe inner diameter, pump pressure and cleaning method before use. Part number 233494001 is used as listed
