The present invention relates to an assembly including an end-fitting and an unbonded flexible pipe, which end-fitting is adapted for connecting the unbonded flexible pipe to a connector. The end-fitting has a through-going opening with a centerline and a front end and a rear end, and the end-fitting further provides for establishing an electrical connection to a least one electrical heating system in the unbonded flexible pipe. Moreover, the end-fitting includes at least one first metallic part having a first surface contacting a second surface of at least one second part in the end-fitting, wherein the first surface of the first metallic part, at least in the vicinity of the through-going opening, includes a coating having a high electrically resistivity. The invention also relates to a method for providing an end-fitting having good properties in respect of reducing galvanic corrosion.
