Extension Universal Joints
Wilson Extension Universal Joints are useful for many applications when expanding tubes through waterwall headers, superheaters, water legs, etc. The integral design eliminates coupling an extension with a separate universal joint. The 140° working angle matches the standard location of many tubes from the accessible hand hole.
