This large reducer will allow you to install the Gutter Mate Diverter & Filter to collect rain water from your 100 or 110mm downpipe. The Reducer is used to connect into the inlet (top) of the Gutter Mate Diverter & Filter to enable the fitting of the filter in to 100mm (4”) diameter downpipe or 110mm downpipe. Gutter Mate 100mm female to 80mm male reducer is available in grey only. Used in applications where the filter is to be fitted to cast Iron, aluminium, steel or plastic down pipes of 100 mm or 110mm diameter. If the downpipe is 110mm diameter an additional adaptor will be needed. Height 30cm Please note the reducer has a taper on the female end of the reducer. When fitting the adaptor, it is fitted with the rubber seal end over the female end of the reducer. Only push the adaptor a little way on to the reducer, if pushed down to the bottom part of the female end it will be slack & subsequently leak. If you want to push it down as far as it will go you will need to build up the OD of the female end of the reducer with insulating tape & then push the adaptor down so the rubber seal will sit on the tape.
