                                    This set consists of PTFE reducing rings graduated in ground joint sizes 14.5 / 18.8 / 24 / 29.2 / 34.5 / 45 and 60. With these rings, different cone and socket sizes can be connected. For example, it is possible to fit a 14.5 cone into a socket of 45.  Also other combinations are possible. With this set you can practically cover all requirements within the lab.
