1/2 inch x 1/8 inch Black Iron Bushing

1/2 Inch x 1/8 Inch Black Iron Hex Bushing – Threaded Reducing Fitting

This 1/2 inch x 1/8 inch black iron bushing is designed for use in threaded piping systems where a reduction in connection size is required. It features male NPT threads on the larger end and female NPT threads on the smaller end, making it suitable for joining components of different diameters within gas, air, or low-pressure water systems.

Product Specifications

• ✅ Material: Black malleable iron
• ✅ End Connections: 1/2 inch male NPT x 1/8 inch female NPT
• ✅ Type: Hex-head bushing for easy wrench application
• ✅ Thread Standard: ANSI/ASME B1.20.1 NPT threads
• ✅ Application: Non-potable water, compressed air, gas lines, or steam (low-pressure only)

Installation Considerations

Use thread sealant or PTFE tape compatible with the system's media and temperature range to ensure leak resistance. Tighten with a properly sized wrench applied to the hex portion of the fitting. Do not overtighten, as excessive torque may lead to thread damage or cracking in adjacent fittings. Ensure alignment with system specifications regarding pressure rating, material compatibility, and service conditions.

Common Applications

• Reducing threaded outlet sizes in black iron gas piping networks
• Installing pressure gauges, drains, or valves with smaller inlet sizes
• Adapting fittings in HVAC and compressed air systems

Material Note

Black malleable iron provides durability and resistance to mechanical shock, making it well-suited for use in gas distribution and industrial systems where corrosion from moisture is limited. This fitting is not approved for potable water systems or for use in corrosive environments without proper protective coatings.

Compliance and Use

• Compliance: Meets applicable ASTM and ANSI dimensional and thread standards for malleable iron fittings
• Environment: Indoor or sheltered above-ground applications only
