Abstract: A fluid connection system for a pump or other fluid handling device includes adapters for connecting fluid lines and fittings of different diameters to a fluid port. The system includes a sliding quick disconnect element with an adapter inserting internally of the quick disconnect element into a bore of the port. The adapter includes a cylindrical body with an outer annular groove that receives an O-ring for sealing against the bore of the port. The adapter body includes a first portion having a first inner diameter and a second portion having a second portion having a second diameter for receiving the fitting from the fluid line. The quick disconnect element receives the adapter internally of the quick disconnect to retain the adapter. The adapters having different diameter internal cavities and may be interchanged for using the same port for fluid lines of different sizes and diameters.
