2 inch x 1-1/4 inch Galvanized Cast Iron Bushing

2" x 1-1/4" Galvanized Cast Iron Bushing – Heavy-Duty Threaded Reducer for Pipe Systems

The 2" x 1-1/4" galvanized cast iron bushing provides a secure threaded transition between differing pipe diameters, facilitating robust system integrity across industrial, commercial, and residential applications. Manufactured from durable cast iron and hot-dip galvanized for enhanced corrosion protection, this reducing bushing is built to perform in both indoor and exposed environments.

Performance Highlights

• ✔️ Material: Cast iron with ASTM A197/A47 compliance for mechanical strength and durability
• ✔️ Protective Coating: Galvanized finish applied per ASTM A153 for corrosion resistance in water and low-pressure systems
• ✔️ Thread Type: Female (2") x Male (1-1/4") NPT per ANSI B1.20.1, ensuring compatibility with standard iron pipe thread systems
• ✔️ Use Case: Ideal for reducing port sizes in pressure-rated piping systems such as water distribution, HVAC, or process lines
• ✔️ Operating Limits: Suitable for non-potable water, air, steam, oil, or gas depending on system configuration and local code

Installation Best Practices

Ensure threads are clean and properly aligned before assembly. Apply thread sealant or PTFE tape to male threads to prevent leaks and galling. Torque should be applied evenly without over-tightening, which may crack mating components. Bushing must be installed within systems compliant with working pressure and temperature limits dictated by the piping material and service fluid.

Typical Applications

Galvanized cast iron bushings are commonly utilized in:

• Branch transitions in water distribution headers
• Valve or equipment port reductions
• Steam or compressed air systems in commercial buildings
• Mechanical pipework requiring rigid, corrosion-resistant reduction fittings

Did You Know?

Galvanized cast iron fittings offer a significant service life advantage over bare cast iron in humid or outdoor installations. Their coating resists rust formation that could otherwise compromise joint integrity over time.

The 2" x 1-1/4" galvanized cast iron bushing combines mechanical strength, dimensional accuracy, and corrosion protection, making it a trusted component for demanding job sites. Engineered to meet code requirements and withstand repeated pressure cycles, this fitting ensures dependable performance in critical transitions.
