PROBLEM TO BE SOLVED: To provide a seal rubber molding having superior permeability resistance against chlorofluorocarbon R134a and durability, and preferable as a seal member against a refrigerant gas including chlorofluorocarbon R134a, and provide a cooling apparatus using the same.SOLUTION: This invention relates to a seal rubber molding 1 used against chlorofluorocarbon R134a. The seal rubber molding 1 is formed by vulcanizing rubber compound containing, under a prescribed rate, acrylonitrile-butadiene copolymer rubber with a prescribed quantity of coupling acrylonitrile, carbon black with a prescribed particle diameter and vulcanizer composed of organic peroxide. In addition, this invention relates to a cooling apparatus provided with a refrigerant pipe where at least chlorofluorocarbon R134a flows as refrigerant, and the seal rubber molding 1 is used at its connecting part. |
