Elbows, also known as “ells,” are used to change the direction of a pipe system. An elbow typically features a 45, 90 or 180 degree bend, although other angles are also available. Elbows come in a variety of diameters and are generally threaded for connectivity. A common example of an elbow fitting in the home is the piece that extends from the wall of your shower to which the shower head connects.

Wall thickness: SCH5 to SCH160When the two ends differ in size, the fitting is called a reducing elbow or reducer elbow.
Elbows are categorized based on various design features as below:
Long Radius (LR) Elbows – radius is 1.5 times the pipe diameter
Short Radius (SR) Elbows – radius is 1.0 times the pipe diameter
90 Degree Elbow – where change in direction required is 90°
45 Degree Elbow – where change in direction required is 45°
Size range: 1/2 to 56 inches (DN 15 to DN 1,400mm)
Degree: 22.5 Deg, 45 Deg, 90 Deg, 180 Deg
