180 Degree Bend

A 180-degree bend, also known simply as a "180 bend" or "180-degree elbow," is a type of pipe fitting used in plumbing, piping systems, and other applications where a change in the direction of fluid flow or the alignment of pipes is required. As the name suggests, a 180-degree bend allows for a complete reversal of the pipe or conduit's direction, creating a U-shaped or hairpin-like configuration.

180-degree bends, like other pipe fittings, are valuable components in piping systems, allowing for changes in direction and alignment while maintaining the integrity of fluid flow. Proper selection and installation are important to ensure the effectiveness and longevity of the piping system.
