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

3" Grooved 90° Long Radius Elbow – Ductile Iron

This 3 inch grooved 90-degree long radius elbow is built for commercial, industrial, and fire protection piping systems that require efficient directional changes. Its longer bend radius helps reduce pressure loss, system noise, and wear, making it a preferred choice for both performance and longevity.

What Is a Long Radius 90° Elbow?

Long radius elbows are designed with a sweeping curve approximately 1.5 times the diameter of the pipe (1.5D). This provides smoother fluid flow, reduces turbulence, and helps maintain consistent pressure in fire sprinkler, HVAC, and mechanical piping applications.
