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

1-1/2 Inch x 1 Inch Black Iron Hex Bushing – Threaded

The 1-1/2 inch x 1 inch black iron hex bushing is designed to reduce fitting or pipe size in threaded iron piping systems. Commonly used in gas, steam, oil, and hydronic heating lines, this component enables a secure reduction in line size while maintaining system integrity.

Product Specifications

• Material: ASTM A-197 malleable iron
• Finish: Black coating for corrosion resistance in non-potable systems
• Thread Type: NPT (National Pipe Taper), female-to-male
• Size: 1-1/2 inch female x 1 inch male
• Compliance: Meets ANSI B16.3 and ASTM A197/A197M specifications

Performance and Application

• Rated for: Use in low-pressure steam, air, gas, and oil systems
• Temperature Range: Suitable for applications up to 150 psi for steam and 300 psi for non-shock water/oil/gas at ambient temperatures
• Threaded Reduction: Allows for reduction in line size while maintaining full mechanical engagement with both mating components

Installation Recommendations

Use compatible thread sealant (pipe dope or PTFE tape) on all male threads to ensure a secure, leak-resistant joint. Over-tightening can result in fitting or pipe failure; always follow torque specifications. Hex head allows for tightening with a standard pipe wrench or adjustable spanner without damaging threads.

Common Use Cases

• Natural gas or propane fuel line reductions
• Steam heating system distribution loops
• Air compressor lines or industrial piping transitions
• Oil and lubricant piping for mechanical systems

Technical Note

While bushings are compact and convenient, consider using reducing couplings for added structural integrity in vibration-prone or high-cycle installations. Not suitable for potable water systems due to the black coating and potential for corrosion in constant moisture environments.

The 1-1/2 inch x 1 inch black iron threaded bushing offers a dependable solution for reducing pipe size while maintaining thread compatibility and mechanical integrity in gas, air, and fluid systems.
