The connector check valve for hydrogenation comprises a first body and a second body, wherein a first internal flow path extending from one end to the other end is formed in the first body; a second body in which a second internal flow path extending from one end to the other end is formed, one end of the second body being coupled to the first body by being inserted into the first internal flow path through the other end of the first body; a sealing member that is disposed in the first internal flow path, seals between the inner peripheral surface of the first body and one end of the second body, and has formed therein a third internal flow path extending from one end to the other end, the third internal flow path guiding hydrogen flowing into the first internal flow path to the second internal flow path; an elastic member disposed in the second internal flow path; and a valve member that is supported by the elastic member, is movably disposed in the second internal flow path, and has a valve portion formed a
