1 x 1/2 inch Black Iron 90 Degree Reducing Elbow Female x Female

1" x 1/2" Black Malleable Iron 90° Reducing Elbow – Threaded FPT

This 1" x 1/2" 90-degree reducing elbow is constructed from black malleable iron and is designed to provide a reliable, pressure-rated transition between different pipe diameters in confined piping layouts. It features two female NPT threaded ends to enable secure directional changes and size reduction in a single fitting.

Commonly used in gas, steam, and oil piping systems, this elbow supports systems requiring consistent mechanical strength and dimensional accuracy. The malleable iron composition offers excellent impact resistance and ductility under varying load conditions, while its black finish is ideal for non-corrosive environments where galvanization is not required.

Product Highlights

• ✅ Size Transition: Reduces from 1" to 1/2" while maintaining flow alignment at a 90° angle

Typical Applications

Frequently installed in commercial and residential systems requiring directional flow changes with a size reduction, this elbow is appropriate for black iron piping networks used in gas distribution, compressed air systems, and general utility piping. Its mechanical performance makes it suitable for concealed or exposed locations where space constraints are a factor.

Field Insight

Malleable iron fittings are preferred in high-load or vibration-prone applications due to their inherent ductility and crack resistance, offering a reliable option for structural or utility piping frameworks.

With proper use of thread sealant or PTFE tape during assembly, this fitting delivers consistent performance in systems where joint integrity and dimensional compatibility are critical.
