A swivel is a connection that allows the connected object, such as a gun or chair to spin horizontally or vertically. A day-to-day design for a swivel is often a cylindrical shaft that can turn freely inside a support structure. The rod is usually kept in place by a nut, washer or by thickening the rod. The apparatus is usually connected to the ends of the rod or the center. Another familiar design is a ball that can revolve, within a support structure.
A third design is an empty cylindrical rod that has another rod that is smaller, inside. They are prevented from separating by flanges. The device could possibly be connected to either end. A swivel joint for a pipe can be a threaded link, in which no less than one of the pipes is bent, often at an angle of 45 or 90 degrees. Their bond is squeezed, enough for being water or air tight and then tightened further.
