2 inch x 3/4 inch Black Iron Bushing

2 Inch x 3/4 Inch Black Iron Hex Bushing – Threaded Reducing Fitting

This 2 inch x 3/4 inch black iron hex bushing is used to reduce pipe size in threaded systems by adapting a larger female threaded opening to a smaller male threaded connection. It is commonly employed in gas, air, and low-pressure water distribution systems where durable, threaded iron fittings are specified.

Material and Standards

• ✅ Material: Black malleable iron per ASTM A197
• ✅ Coating: Black oxide finish for indoor or low-moisture applications
• ✅ Thread Standard: ANSI/ASME B1.20.1 NPT (National Pipe Tapered Thread)
• ✅ Configuration: 2 inch male NPT x 3/4 inch female NPT
• ✅ Head Style: Hexagonal for wrench installation and removal

Application Considerations

Designed for use in non-potable piping systems, this fitting is suitable for fuel gas lines, steam, air compression systems, and general mechanical piping. It is not intended for use in potable water systems unless certified as lead-free. Use with compatible malleable iron, cast iron, or steel pipe and fittings.

Installation Requirements

• ✅ Sealing Method: Apply thread sealant or PTFE tape to male threads to ensure a leak-resistant joint
• ✅ Wrench Engagement: Use appropriate hand tools on hex surfaces only; avoid applying torque to pipe body
• ✅ System Pressure: Ensure system pressure does not exceed manufacturer or code limits for Schedule 40 threaded iron fittings

Typical Uses

• Reducing connections in black iron gas distribution systems
• Adapting down to control devices, regulators, or gauges in mechanical systems
• Installed in hydronic heating, compressed air, or industrial gas piping networks

Additional Notes

Black iron bushings provide a robust, code-compliant method for reducing threaded connections in applications not requiring corrosion-resistant or potable water fittings. For environments with exposure to moisture, consider galvanized alternatives or additional protective coatings as required by project specifications.
