2 inch Black Iron 45 Degree Elbow Female x Female

2 inch Black Malleable Iron 45° Elbow – Threaded Directional Fitting for Gas and Hydronic Systems

The 2 inch Black Malleable Iron 45-Degree Elbow provides a durable and mechanically secure solution for changing flow direction in threaded steel piping systems. Designed to accommodate angular transitions while maintaining pressure integrity, this fitting is well-suited for use in gas distribution, air compression lines, and hydronic heating loops.

Manufactured in accordance with ASME B16.3, this malleable iron elbow features precision-machined female NPT threads and a corrosion-resistant black finish. It supports consistent performance in both horizontal and vertical piping arrangements and is rated for use in a variety of non-potable systems requiring directional shifts without compromising flow rate or joint stability.

Product Features

• ✅ Nominal Size: 2-inch
• ✅ Material: ASTM A197 black malleable iron, suitable for mechanical strength and moderate corrosion resistance
• ✅ Connection Type: Female NPT x Female NPT (threaded per ANSI/ASME B1.20.1)
• ✅ Angle: 45 degrees for directional flow transitions
• ✅ Coating: Black oxide finish for interior installations or dry system environments

Performance Advantages

• ✅ Pressure-Rated Thread Integrity Engineered to form leak-resistant joints in low- to medium-pressure systems using compatible male-threaded steel piping.
• ✅ Dimensional Precision Tapered threads allow for proper torque application, supporting system alignment and minimizing thread wear during installation.
• ✅ System Versatility Suitable for sealed gas lines, HVAC risers, steam condensate routing, and compressed air systems.
• ✅ Code Compliance Typically meets requirements for use in mechanical systems governed by NFPA, ASME, and IPC codes.

Installation Recommendations

Threaded elbow installation should be conducted using pipe wrenches and appropriate thread sealant or PTFE tape. Ensure threads are clean and free of debris prior to assembly. Tighten to specification using calibrated torque where required. Follow system pressure testing protocols after installation in accordance with local mechanical codes.

Typical Applications

This 45° elbow is commonly deployed in installations where directional change is needed within confined layouts or to accommodate structural offsets. Frequent use cases include branch line transitions in gas service systems, boiler loop offsets, and equipment connection headers.

Technical Advisory

Black malleable iron fittings are not intended for use in potable water systems. They are optimized for structural integrity and pressure resistance in utility-grade and industrial service lines.

The 2 inch Black Malleable Iron 45° Elbow offers a professional-grade solution for directional changes in threaded piping networks where consistent performance and code-compliant connections are required.
