2-1/2 inch x 1-1/2 inch Black Iron Bushing

2-1/2 Inch x 1-1/2 Inch Black Malleable Iron Reducing Bushing – Threaded

This 2-1/2 inch x 1-1/2 inch black malleable iron reducing bushing is designed for threaded pipe transitions where size reduction is required. Manufactured to ANSI and ASTM standards, this fitting provides dependable mechanical strength and sealing capability in a range of pressure-rated piping systems.

Product Overview

Reducing bushings are commonly used to connect larger diameter pipe to smaller threaded fittings in natural gas, steam, or water lines. This component features male threads on the larger end and female threads on the reduced side, machined to tight tolerances for leak-resistant assemblies.

Key Features

• Material: Black malleable iron, ASTM A197
• Surface Finish: Uncoated (black), intended for non-corrosive environments or gas systems
• Connection Type: NPT male x NPT female (ANSI B1.20.1 standard taper threads)
• Pressure Rating: Up to 150 psi for steam and 300 psi for non-shock water, oil, or gas
• Temperature Range: Suitable for systems operating up to 650°F depending on application
• Design Standard: Conforms to ANSI/ASME B16.3 for dimensional compatibility

Performance Considerations

• ✔️ Precision Machining – Threads are CNC-cut for uniformity and proper engagement, minimizing joint leakage
• ✔️ System Compatibility – Interfaces seamlessly with steel pipe and other ferrous components in fuel gas, air, or liquid service
• ✔️ High Structural Integrity – Durable body resists cracking and deformation under torque loads

Installation Guidance

Apply pipe joint compound or approved PTFE thread sealant to ensure a tight, pressure-rated seal. Wrenches should be applied only to the hexagonal section of the bushing—avoid over-tightening, which can lead to thread damage or deformation. Not suitable for use in potable water systems without additional corrosion protection or coating.

Common Applications

• Natural gas and LP piping systems
• Low-pressure steam lines
• Compressed air and non-potable water systems
• Oil distribution piping in mechanical or industrial facilities

Note:

This black iron bushing is intended for systems where corrosion resistance is not a primary concern. For environments with high humidity or moisture, galvanized or coated alternatives should be considered to prevent long-term degradation.
