1-1/4 inch x 3/4 inch Black Iron 90° Reducing Elbow – Threaded FIP x FIP
The 1-1/4 inch x 3/4 inch Black Iron 90-Degree Reducing Elbow is designed to transition between pipe sizes at right angles while maintaining system integrity. Manufactured from durable black malleable iron, this elbow fitting is suitable for use in non-potable water, oil, steam, air, and gas systems.
Threaded Female National Pipe Thread (NPT) connections on both ends allow for compatibility with a wide range of system configurations. It provides mechanical strength, dimensional consistency, and corrosion resistance required in high-pressure environments.
Product Features
- Material: Malleable black iron
- Connection Type: Female NPT x Female NPT
- Size: 1-1/4 inch x 3/4 inch
- Angle: 90 degrees for directional flow change
- Standard Compliance: Meets or exceeds ASTM A197 and ANSI/ASME B16.3
- Surface Finish: Black oxide coating for basic corrosion resistance
Installation Guidelines
This reducing elbow should be installed using standard threading procedures with an appropriate thread sealant or PTFE tape. It is critical to maintain proper torque during installation to prevent thread damage and ensure a leak-tight seal. Suitable for installation with Schedule 40 or Schedule 80 steel pipe and fittings.
Typical Applications
- Natural gas distribution systems
- Steam piping in mechanical rooms
- Compressed air systems
- Hydronic heating infrastructure
- Oil and fuel service lines
Key Performance Advantages
- Enables transitions between larger and smaller diameter pipe sections
- Maintains directional flow without the need for additional adapters
- Provides structural reliability in high-pressure and elevated-temperature systems
Additional Considerations
This fitting is not rated for use in potable water systems due to the absence of protective galvanization. For applications requiring corrosion resistance in moisture-prone environments, consider using galvanized or brass alternatives. Avoid use with plastic or copper piping unless an approved dielectric union is utilized.
The 1-1/4 inch x 3/4 inch Black Iron Reducing Elbow is a core component in traditional pipe-joined mechanical systems, offering dependable performance and versatility across industrial, commercial, and residential environments.
