These filters are useful in conjunction with the larger pumps which use bigger conjunction parts i.e. 3/8″. All filters use a detachable bowl and a replaceable element inside. The housing of the filter comes complete with a surface mounting bracket, this bracket can be mounted either side of the housing. There are five connection sizes available with each size having the option of a standard length bowl and filter or a long style bowl and filter. Elements for all filters can be ordered separately.
