The 9mm or 6mm Golf Filter is for use with 30 L & 47 L plastic reservoirs. It is inserted into the pipe end inside the reservoir once the pipe is pushed through the Top Hat Grommet. It can be easily serviced and will float to the top if it comes detached from the tube, this will not happen if you make sure you have pushed the filter firmly into the tube.
