A dielectric fitting (10, 10′, 110) assembly includes a hose (14, 114) connected between two end fittings (12, 121, 112), and a structural reinforcement portion having at least an inner layer (26, 26′,126) formed of a first composite material having a high strength and a second composite material having a high electrical resistance. The first and second composite materials cover the assembly and provide a smooth transition of radial stiffness as the inner layer transitions from a high strength portion to a high electrically resistant portion.
