Elastomer for a fluid transport pipe such as for example a pipe of an air conditioning circle for an automobile vehicle, the elastomer being essentially formed by a isobutilene therpolymer, of paramethylstyrene and of parabromiummethylstyrene associated before the vulcanization of an absorbent agent of the acidity, this elastomer has after the vulcanization a weak reminent formation in compression guaranteeing the airtightness of the assembly of a pipe on a rigid retailer connection.
