ABSTRACT:
The invention provides a coupling device for high pressure threaded pipe connection to a coupling body with a standard 24 degree connector, a coupling nut to establish a pressure tight connection and a shaped pipe or a connection stub for connection to other system components. An adapter ring is proposed with a cylindrical internal bore and radially progressing and/or domed end ring faces of different sizes, at least one of which is formed as a sealing face fitted with a ring seal, to each of which an axially directed cylinder outer face is juxtaposed, between which a 24.degree. outer bevel is arranged to adapt to the coupling body. The ring face of the adapter ring which when fitted is directed towards the connection stub or the flared flange of the shaped pipe is provided with an annular groove to accept a ring seal or an o-ring.
