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

1-1/4" x 1/2" Galvanized Iron Bushing – Heavy-Duty Reducing Fitting for Pressure Applications

The 1-1/4" x 1/2" Galvanized Iron Bushing is a durable reducing fitting designed to connect pipes of dissimilar sizes in threaded pressure systems. Manufactured from malleable cast iron and hot-dip galvanized to ASTM A153 standards, this bushing is engineered to deliver strength, corrosion resistance, and dimensional accuracy for long-term performance in both residential and industrial settings.

Core Performance Benefits

• Threaded Reduction: Reduces a 1-1/4" female threaded opening to accommodate a 1/2" male threaded pipe, ideal for tight installations or equipment connections.
• Galvanized Protection: Hot-dipped zinc coating safeguards against corrosion, extending fitting lifespan in humid or outdoor environments.
• Malleable Cast Iron Body: Conforms to ASTM A197, offering excellent mechanical strength and fracture resistance under pressure or vibration.
• Precision NPT Threads: Manufactured to ANSI B1.20.1 for consistent engagement, sealing, and compatibility with standard piping systems.
• Compact Profile: Hex-head design allows for easy tightening and wrench accessibility during installation.

Installation Guidance

Apply an approved thread sealant or PTFE tape to male threads prior to installation. Hand tighten and follow with wrench tightening to manufacturer torque specifications. Avoid over-tightening, which may damage threads or distort sealing surfaces. Inspect threads for burrs or contamination before use.

Did You Know?

Bushing fittings like this one allow systems to be downsized efficiently without requiring additional fittings, saving space and reducing the number of joints—two critical factors in minimizing leak potential.

The 1-1/4" x 1/2" Galvanized Iron Bushing is engineered to provide secure, pressure-rated performance with the added benefit of corrosion resistance. When strength and reliability are non-negotiable, this fitting delivers proven performance in demanding pipe networks.
