Do you have a pool cartridge filter that contains only one filter cartridge inside? If so, then you will need the Cyclone Adapters to fit on the inside of the filter.
Some of these larger sized single cartridges have an opening of 4″ and others are 6″. These Adapters accommodate both of these sizes.
They require that you have a Cyclone Filter Cleaning System to use them as they nest with the retainers included in that system. If you have a cartridge filter with 4 elements inside then you do not need these adapters.
Includes:- Top XL Adapter
