An electrical isolator comprising: a first fluid-carrying member and a second fluid-carrying member spaced apart from said first fluid-carrying member; wherein said first fluid-carrying member has a first toothed surface and said second fluid-carrying member has a second toothed surface; wherein the electrical isolator further comprises: a fibre-reinforced polymer tube that overlaps both the first fluid-carrying member and the second fluid-carrying member and which contacts the first toothed surface in a first interface region of the fibre-reinforced polymer tube and which contacts the second toothed surface in a second interface region of the fibre-reinforced polymer tube; and a compression fitting arranged to bias the first interface region and the first toothed surface together. Conventional electrical isolators require complex multi-part unidirectional seals to prevent leakage of the fluid. Such seals are expensive as well as being difficult, complicated and time-consuming to assemble. By mating the fibre-reinforced polymer tube with the first and second fluid-carrying members by a toothed interface the two parts of which are biased together by means of the compression fitting, the fluid-carrying members and the fibre-reinforced polymer tube are brought into sufficiently firm contact that a good seal is made and maintained, thus preventing leakage of the fluid during use.
