About this item

The BK Products Model 520-143HN is a high-quality black iron 90-degree reducing elbow, designed to connect two male-ended pipes of differing diameters in high-pressure, non-potable piping systems. This fitting is part of BK Products’ Southland line of malleable iron components, engineered for strength, reliability, and compliance with industry standards.

Its compact design and precision threading make it ideal for installations requiring directional changes and size transitions, especially in fuel, lubricant, steam, and gas transport systems. The elbow is not intended for potable water use but excels in industrial and mechanical applications.
