The end to center measurement of a 90-degree long radius elbow is typically what size?

The end to center measurement of a 90-degree long radius elbow, known for its smooth turn and ability to reduce turbulence in fluid flow, is typically 1-1/2 inches NPS (Nominal Pipe Size). This measurement reflects the distance from the end of one pipe fitting to the center of the elbow, which is crucial for ensuring proper alignment and fitting in piping systems.

Understanding the significance of the long radius elbow is essential, as it allows for better flow characteristics compared to short radius elbows. In many applications, such as HVAC and hydronic systems, ensuring a proper fit and minimizing pressure drop is critical. The 1-1/2 inches NPS measurement is standardized, which means it adheres to industry specifications, making it a reliable choice for engineers and contractors in the field.
