A sealing system with sealing ring for coupling members for connecting pipes to user devices such as pumps, compressors, tanks and the like, by means of a shank that screws into a seat provided on the said user devices, comprises a groove and an annular seal. The groove, which is shaped according to the teaching of international standard ISO UNI 5711-65, is situated in a position adjacent to the shank of the coupling member, at the opposite end from the end of the shank. The groove is able to receive the annular seal designed to be pressed against an abutting wall or a flared portion of the seat of the user device in order to establish the seal. In the original configuration prior to assembly, the sealing ring is of an essentially cylindrical shape, whereas, in the configuration of compression on the groove, it assumes a shape adapted to the profile of the groove, which is generally frustoconical.
