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

1-1/2" x 1" Galvanized Cast Iron Bushing – Engineered for Tough, Long-Term Performance

The 1-1/2" x 1" Galvanized Cast Iron Bushing is built for adapting pipe sizes in high-demand piping systems where mechanical strength and corrosion resistance are essential. This fitting reduces a 1-1/2" female threaded opening down to a 1" male thread, allowing seamless integration between dissimilar pipe sizes in fluid conveyance systems.

Application Advantages

• ✔️ Corrosion-Resistant Galvanized Coating – Hot-dip galvanization protects the cast iron substrate from rust, ideal for humid or corrosive environments.
• ✔️ Thread Integrity – Tapered NPT threads meet ANSI B1.20.1 standards, promoting tight seals with thread sealant or PTFE tape.
• ✔️ Heavy-Wall Cast Iron – Provides rigidity and structural strength for installations subject to pressure fluctuations or mechanical stress.

Specifications

• Material: Galvanized cast iron
• Size: 1-1/2" female NPT x 1" male NPT
• Connection Type: Threaded (National Pipe Thread Tapered)
• Standard Compliance: ASME B16.3 for fittings, ASTM A197 for castings

Installation Considerations

Installation of threaded cast iron bushings should be done with proper sealing techniques and tools. Avoid over-tightening to prevent stress cracking or thread deformation. Apply a thread sealant approved for metal-to-metal connections to prevent leaks. Confirm alignment and torque limits according to application pressure ratings.

Common Use Cases

This bushing is typically found in water distribution lines, compressed air systems, and mechanical piping networks. It’s especially effective where pipe size transitions are needed without sacrificing strength—such as boiler rooms, utility areas, or industrial process lines.

Did You Know?

Galvanized cast iron bushings offer a cost-effective solution for corrosion-resistant connections and are frequently used in applications where full stainless steel components are not required but durability remains a priority.

The 1-1/2" x 1" Galvanized Cast Iron Bushing offers reliable service life, precise threading, and the strength to meet rigorous system demands. Trusted by mechanical contractors for its fit, finish, and long-term reliability, this component remains a staple for pipe size reductions in durable plumbing systems.
