2-1/2 inch x 1-1/4 inch Black Iron Bushing

2-1/2 Inch x 1-1/4 Inch Black Iron Hex Head Bushing – Threaded Reducing Fitting

The 2-1/2 inch x 1-1/4 inch Black Iron Bushing is a hex-head, threaded reducing fitting used in piping systems to transition between larger and smaller nominal pipe sizes. Constructed from black malleable iron, it is designed for use in non-potable water, steam, air, and gas applications requiring strong mechanical connections and dimensional integrity.

Material and Design Characteristics

Engineered for compatibility with standard pipe threads, this fitting provides a rigid and corrosion-resistant connection within a wide range of industrial and commercial mechanical systems:

• ✅ Material: Malleable black iron (ASTM A197)
• ✅ Connection: 2-1/2 inch male NPT x 1-1/4 inch female NPT
• ✅ Head Style: Hex head for wrench engagement and torque control
• ✅ Thread Standard: ANSI/ASME B1.20.1 (National Pipe Taper Thread – NPT)
• ✅ Pressure Rating: Up to 300 PSI non-shock for water/oil/air (WOG), 150 PSI for steam service

Installation Requirements

Threaded installation requires a compatible male-threaded fitting and application of an approved thread sealant or PTFE tape to ensure a leak-resistant seal. Use proper torque to avoid thread deformation. Always verify compatibility with adjacent system materials and confirm conformance with local plumbing and mechanical codes.

Typical Applications

This reducing bushing is commonly used in the following systems:

• Gas piping (verify compliance with local code and jurisdictional approval)
• Low- to medium-pressure water lines
• Steam and hydronic heating systems
• Compressed air distribution systems

Performance Considerations

Black iron fittings are preferred for gas and oil service due to their strength and resistance to internal corrosion when exposed to non-potable media. The hex-head design provides installation flexibility and facilitates secure mechanical tightening using standard hand tools.

The 2-1/2 inch x 1-1/4 inch Black Iron Hex Head Bushing offers a durable, threaded solution for reducing line size while maintaining pressure integrity across various industrial, commercial, and utility piping systems. It meets established manufacturing and performance criteria for safe and effective fluid and gas handling.
