1/4 inch x 1/8 inch Black Iron Bushing

1/4 Inch x 1/8 Inch Black Iron Hex Head Bushing – Threaded Reducing Fitting

The 1/4 inch x 1/8 inch Black Iron Bushing is a hex-head reducing fitting used to connect pipe or fittings of different sizes within threaded systems. Commonly applied in natural gas, air, oil, and low-pressure steam lines, this bushing is made for installations requiring strength, dimensional accuracy, and reliable thread engagement.

Product Characteristics

Designed in accordance with industry standards for malleable iron pipe fittings, this component provides mechanical transition without compromising system pressure integrity:

• ✅ Malleable Iron Construction: Formed from ASTM A197-grade black iron with uniform wall thickness and strength suitable for mechanical and utility systems.
• ✅ NPT Threading: Male and female threads machined to ANSI B1.20.1 standards for compatibility with standard steel, iron, or brass piping.
• ✅ Hexagonal Head: Allows installation with a wrench for proper torque application during tightening.
• ✅ Corrosion Resistance: Black iron finish provides a degree of surface protection in non-corrosive indoor applications.

Contractor-Oriented Features

• ✅ Dimensional Accuracy: Machined for consistent thread depth and engagement, reducing misalignment during connection.
• ✅ Thread Integrity: Engineered for reliable sealing with approved thread sealant or PTFE tape.
• ✅ System Versatility: Compatible with fuel gas, compressed air, and general-purpose liquid piping systems not requiring lead-free compliance.

Specifications

• Material: Black malleable iron
• Size: 1/4 inch male NPT x 1/8 inch female NPT
• Type: Hex head bushing, reducing
• Standards: ANSI B16.3, ANSI B1.20.1 compliant
• Pressure Rating: Up to 150 psi for steam, 300 psi for air/water (non-shock)

Common Applications

Used in mechanical rooms, utility corridors, fuel gas systems, and compressed air lines, this fitting provides a durable solution for size reduction where compact layout and system compatibility are required. Typical environments include boiler rooms, shop air distribution, and gas manifold configurations.

Installation Guidance

Ensure that mating threads are clean and apply an appropriate thread sealant. Use a properly sized wrench on the hex head to avoid over-torquing or deformation. Installation should follow applicable mechanical or fuel gas codes based on the system type.

The 1/4 inch x 1/8 inch Black Iron Hex Head Bushing is a standard component in threaded steel piping systems, offering a reliable and code-conforming method for reducing connection sizes while maintaining system performance and structural integrity.
