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

1/2 inch Black Iron 90° Elbow – Threaded Elbow for Gas and Hydronic Piping Systems

The 1/2 inch Black Iron 90° Elbow is a threaded malleable iron fitting used for making directional changes in black pipe systems. Designed for use in gas distribution, hydronic heating, and low-pressure steam applications, this elbow provides a durable and secure 90-degree transition between two threaded pipe sections.

Manufactured from ASTM A197 malleable iron and finished with a black oxide coating, this elbow offers excellent mechanical strength and corrosion resistance in non-potable service conditions. Threads conform to ANSI B1.20.1 standards for tapered pipe threads, ensuring consistent fit and sealing performance.

Product Features

• ✅ 90° Elbow Design – Creates a right-angle change in direction within a piping layout.
• ✅ Threaded F x F Connections – Female NPT threads on both ends for compatibility with standard black steel pipe.
• ✅ Malleable Iron Construction – Conforms to ASTM A197; provides excellent ductility and pressure resistance.
• ✅ Black Coating – Protects against oxidation during storage and handling; intended for indoor use in gas and oil piping systems.
• ✅ Industry Standard Threads – Threads machined to ANSI B1.20.1 for dependable engagement and sealing.

Installation Guidelines

Thread sealant or PTFE tape is recommended on male threads prior to tightening. Install using standard pipe wrenches, ensuring that the fitting is not over-torqued to prevent thread deformation or cracking. Verify all connections with appropriate leak detection procedures, especially in gas service.

Common Applications

Widely used in black pipe systems for natural gas, LP gas, compressed air, fire sprinkler lines, and hydronic heating. Frequently installed in mechanical rooms, boiler connections, appliance hook-ups, and retrofit gas line extensions.

Code Consideration

Black malleable iron fittings are generally approved for above-ground gas service installations in accordance with International Fuel Gas Code (IFGC) and local authority requirements. Not intended for potable water use.

The 1/2 inch Black Iron 90° Elbow offers a reliable solution for right-angle directional changes in threaded gas and hydronic piping systems. Engineered to meet industry performance standards, it supports safe, long-term system integrity in a wide range of mechanical applications.
