2 inch x 1-1/2 inch Galvanized Cast Iron Bushing

2" x 1-1/2" Galvanized Cast Iron Bushing – Threaded Pipe Reducer for Pressure Systems

The 2" x 1-1/2" Galvanized Cast Iron Bushing is engineered to provide a durable transition between pipe sizes in threaded piping systems. Commonly used in water, steam, air, and oil service lines, this bushing reduces a 2-inch female pipe thread to a 1-1/2-inch male connection while maintaining structural integrity under pressure.

Manufactured from cast iron and galvanized according to ASTM A153, this fitting offers extended service life through enhanced corrosion resistance. It conforms to ANSI/ASME B16.3 and B16.14 dimensional and threading standards, ensuring a secure fit and interchangeability across compliant systems.

Performance Features

• ✅ Galvanized Coating – Provides zinc-based protection against corrosion in humid or outdoor environments.
• ✅ Cast Iron Body – Supports mechanical loads and withstands working pressures typical of industrial and commercial fluid systems.
• ✅ Threaded Connection – Tapered National Pipe Thread (NPT) for reliable mechanical sealing when installed with approved thread sealants.
• ✅ Size Transition – Effectively reduces nominal pipe size from 2" FIP to 1-1/2" MIP in confined installations or retrofits.

Specifications

• Material: Cast iron, hot-dip galvanized
• Nominal Sizes: 2" female x 1-1/2" male
• Thread Type: NPT (ANSI/ASME B1.20.1)
• Standards: ASTM A153, ANSI/ASME B16.3, B16.14
• Application: Pressure-rated piping systems – water, steam, gas, air

Installation Guidelines

Apply pipe thread sealant or PTFE tape on male threads before installation. Use compatible wrenches on both fitting and mating pipe to avoid overtightening or misalignment. This bushing is intended for use in systems operating within rated pressure and temperature limits as specified by applicable codes.

Common Applications

• Hydronic heating systems
• Steam supply lines
• Compressed air systems
• Potable and non-potable water distribution

Note:

Galvanized cast iron fittings are not recommended for aggressive chemical services or highly acidic wastewater due to potential coating degradation. Always verify material compatibility with project specifications.

The 2" x 1-1/2" Galvanized Cast Iron Bushing offers a robust and code-compliant method for reducing line diameter in pressurized systems while maintaining mechanical integrity and corrosion protection. It is an essential component for contractors working in commercial and industrial settings where reliability and standardization are critical.
