8" Grooved 90° Long Radius Elbow – Ductile Iron, UL/FM Approved

8" Grooved 90° Long Radius Elbow – Ductile Iron

The 8 inch grooved 90-degree long radius elbow is built for heavy-duty fire protection, HVAC, and mechanical piping systems requiring efficient directional flow. With its extended bend radius, this fitting reduces internal turbulence, lowers friction loss, and supports long-term system performance in high-volume pipelines.

What Is a Long Radius Elbow?

A long radius elbow provides a smoother change in direction than a short radius elbow, typically with a bend radius of 1.5 times the pipe diameter. This design reduces stress on the system, helps maintain fluid velocity, and minimizes the risk of erosion, making it ideal for large-diameter piping networks.
