ABSTRACT:
A junction adapter having a hexagonally-shaped central support portion or body is disclosed for use with a conventional plural line clamping assembly. The hexagonal shape of the adapter body provides many advantages over the rectangularly-shaped bodies of prior art junction adapters. Among the advantages are that such adapters can be easily and very economically made from hexagonal bar stock, using conventional automatic screw machines. The use of the hexagonal bar stock results in a junction adapter formed of one piece of metal and thus provides an adapter that does not have any connection joint that can break away. The hexagonal adapter can be oriented in any position and even be slightly misaligned while still being secured firmly within a plural line clamping assembly.
Three embodiments of the hexagonally-shaped adapter are disclosed, and each includes a hexagonally-shaped body, two co-axial connection members, and an axially arranged fluid passages through the junction adapter. Each of the three embodiments employs a different type of male or female threaded connection on its connection members. Two of the three embodiments also include wrench flats on the connection members that allow the hexagonal adapter to be firmly grasped by a wrench so to avoid transmitting torques through to the plural line clamping assembly when a fluid line is being connected to the adapter member.
