An isolator 100 for an aircraft fuel tank configured to separate an electrically conductive internal panel (1, figure 2) of the fuel tank from an electrically conductive pipe (4) that passes through the panel. The isolator comprises a plurality of first attachment points 110 and a plurality of second attachment points 120 for attaching the isolator to the pipe, and an aperture 130 defined by an outer wall 140 and extending from a first side 102 to a second side 104 of the isolator, the aperture configured to receive the pipe in use, wherein the isolator comprises a non-electrically conductive material. The aperture may extend outwardly from the first side to form a tube. First and second attachment point are preferably are positioned on a flange extending from the outer wall. The attachment points may comprise counterbores. There may be a groove on either or both sides round the outer wall to facilitate a seal. Also disclosed is an isolation system, an aircraft and a method of isolating an electrically conductive internal panel or an aircraft fuel tank from an electrically conductive pipe that passes through the panel.
