Where is the Pipe joint addon in Blender 2.7.3? Hi i'm searching this option at User preferences - Addons, but i can't find it in the new version, even making a search. Has been deleted form blender 2.7.3? I want to turn it on as in older versions.
This is now located under Extra Objects in the Add Mesh category.


Once you enable it, you can access the custom primitive types with ShiftA > Pipe Joints.

EDIT:

On version 2.79 Pipe Joints are on Add>Mesh>Mechanical>Pipe Joints
