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

2" x 1-1/2" Black Malleable Iron Hex Bushing – NPT Threaded Reducing Fitting

The 2" x 1-1/2" black malleable iron bushing is a hex-head reducing fitting designed for threaded pipe systems in mechanical, HVAC, gas, and industrial applications. Its purpose is to reduce a larger pipe size down to a smaller one while maintaining a strong, pressure-rated connection.

Manufactured from ASTM A197 malleable iron and conforming to ANSI/ASME B16.3 and B1.20.1 standards, this fitting is suitable for use in non-potable water, air, steam, and gas distribution systems. The hex head provides wrench grip during installation, and the tapered National Pipe Thread (NPT) design helps ensure leak-tight seals when used with approved thread sealants.

Performance and Engineering Features

• ✅ Malleable Iron Body – Delivers high tensile strength and resistance to thermal distortion in high-pressure systems.
• ✅ Threaded Connection (M x F) – NPT tapered threads support a pressure-tight seal for secure pipe reductions.
• ✅ Hexagonal Head – Facilitates tool access in confined installations for reliable torque application.
• ✅ Black Finish – Ideal for indoor use in fuel gas, compressed air, and hydronic heating lines; not rated for potable water without protective lining.

Installation Guidelines

Install the bushing using standard pipe wrenches or adjustable tools. Thread sealant or PTFE tape is required to prevent leakage and ensure thread engagement. Do not overtighten, as excessive torque may cause cracking or thread deformation. This fitting is intended for use in stationary mechanical systems and should not be subjected to vibration without proper support.

Typical Use Cases

• Gas distribution in commercial and light industrial piping systems
• Air compressor lines, mechanical equipment connections
• Water supply reductions in hydronic heating circuits
