Abstract:
PROBLEM TO BE SOLVED: To effectively prevent electrolytic corrosion at an intermediate part between a male thread part and a flange part concerning a connector at a pipe end part made of aluminum of an oil cooler for power steering.
SOLUTION: This electrolytic corrosion preventor is in a connector 4 of an oil cooler having a cylindrical male thread part 4a made of aluminum with a flair nut 6 comprising iron or copper fitted thereinto. A coating film layer 7 is formed on a non-thread part 4c on the side opposite to the direction in which the nut 6 is fitted onto the male thread part 4a to cover and at a part on the side of the non-thread part 4c at the male thread part 4a while an electrically insulating and heat resistant electrolytic corrosion layer 8 is formed inside or outside the coating film layer 7 of the non-thread part 4c.
