3/4 inch x 1/4 inch Galvanized Cast Iron Bushing

Galvanized Cast Iron Bushing – 3/4 inch x 1/4 inch Threaded Reducing Fitting

The 3/4 inch x 1/4 inch Galvanized Cast Iron Bushing is a threaded reducing fitting used to connect pipes of dissimilar nominal diameters. Its compact form factor is ideal for tight spaces where a concentric size reduction is needed within iron pipe systems. Engineered for use in water, gas, air, and other non-corrosive piping applications, it maintains strength under mechanical and pressure stresses.

Manufactured from cast iron and zinc-coated for corrosion resistance, this fitting is compatible with standard malleable iron and steel threaded pipe systems. Typical use cases include mechanical rooms, compressed air lines, hydronic systems, and low-pressure gas piping configurations.

Functional Attributes

• ✅ Threaded Design: NPT female-to-male connection ensures standardized engagement with compatible components.
• ✅ Galvanized Coating: Hot-dip zinc coating protects against moisture-induced oxidation in non-submerged environments.
• ✅ Material Integrity: Cast to ASTM A197 specifications for malleable iron, suitable for mechanical and plumbing system integration.
• ✅ Dimensional Precision: Manufactured to meet ANSI standards for uniformity and seal reliability.
• ✅ Pressure-Rated: Suitable for use in systems operating at moderate pressures per applicable code guidelines.

Specifications

• Size: 3/4 inch Male x 1/4 inch Female (Threaded)
• Material: Galvanized Cast Iron
• Thread Standard: ANSI/ASME B1.20.1 NPT
• Compliance: Fabricated to industry performance and dimensional standards

Installation Considerations

Install using standard threading practices. Apply thread sealant or PTFE tape to male threads before engagement. Avoid excessive torque to prevent damage to threads or surrounding components. For optimal sealing and code compliance, fittings should be installed per project specifications and local plumbing or mechanical codes.

Common Applications

This bushing is typically used in systems requiring a reduction in line size, such as equipment hook-ups, control valve transitions, and termination points. It supports use in residential, commercial, and industrial fluid handling applications where corrosion protection and mechanical strength are priorities.

Material Insight

Galvanized cast iron is frequently specified for threaded systems exposed to ambient moisture or atmospheric oxidation. The zinc coating delays corrosion while maintaining the load-bearing properties of traditional cast iron, extending the life of connections in non-buried installations.

The 3/4 inch x 1/4 inch Galvanized Cast Iron Bushing is a dependable solution for pipe size transitions in threaded systems where compact form and corrosion resistance are required.
