Abstract

A reducer 200 for coupling pipes 11, 111 of different diameter comprises a first hollow cylindrical body 230 with an external annular rib 234 to limit insertion of the body 230 into a bore of an externally threaded coupling member 1 joined to the wider pipe 11 and to abut with an inner flange 241 of an internally threaded sleeve 205 screwed on to the coupling member 1 to join the reducer 200 to the coupling member 1, an annular wall 242 at that end of the hollow cylindrical body 230 opposite the end inserted into the coupling member 1 joining the body 230 to a second hollow cylindrical body 202 for receipt of the pipe 111 coaxial with the first body. Pipes 11, 111 are each held by a joint comprising a clamping ring 9, 109, a sealing ring 20, 120 and a spacing ring 19, 119 compressed axially by a tapered nut 5, 105. <IMAGE>
