The Elbow 17 X 45 is offered by us that is installed between two lengths of pipe (or tubing) to allow a change of direction, usually a 90° or 45° angle; 22.5° elbows are also available. The ends may be machined for butt welding , threaded (usually female), or socketed. When the ends differ in size, it is known as a reducing (or reducer) elbow. The Elbow 17 X 45 is very efficient and made for commercial and industrial uses.
