3/4 inch x 1/2 inch Galvanized Cast Iron Bushing

3/4" x 1/2" Galvanized Cast Iron Hex Bushing – Threaded Reducing Fitting

The 3/4" x 1/2" Galvanized Cast Iron Hex Bushing is engineered to transition between larger and smaller nominal pipe sizes in threaded systems. Constructed from cast iron and hot-dip galvanized for corrosion resistance, this reducing fitting is built for long-term durability in both residential and commercial applications.

Designed in accordance with ANSI B16.3 and threaded per ANSI B1.20.1 standards, this fitting offers secure, leak-resistant connections in a wide range of piping systems. The hexagonal head provides a wrench grip for easy installation and disassembly during maintenance or reconfiguration.

Key Performance Characteristics

• Material: Cast Iron, hot-dip galvanized per ASTM A153
• Size: 3/4" Male NPT x 1/2" Female NPT
• Standards: Meets or exceeds ANSI/ASME B16.3 and B1.20.1
• Design: Reducing bushing with hex head for tool engagement
• Service Rating: Suitable for systems up to 300 PSI non-shock water, oil, or air (WOG)

Application Scope

This galvanized bushing is commonly used in pressure-rated water distribution, compressed air systems, and industrial fluid handling applications. It is also suitable for mechanical and HVAC systems where a reliable, corrosion-resistant threaded fitting is required. Galvanized cast iron components are not recommended for underground or potable water systems due to lead content and corrosion potential over time.

Installation Considerations

• Use with standard NPT-compatible components
• Apply PTFE thread sealant tape or anaerobic thread compound during installation
• Avoid overtightening to prevent thread distortion or cracking
• Not suitable for use with natural gas unless code-approved for the specific application

Advantages

• High Mechanical Strength: Maintains performance under mechanical stress and system vibration
• Corrosion Protection: Zinc galvanization improves resistance to moisture and atmospheric conditions
• Hex Body: Facilitates tightening and removal with standard wrenches
• Standardized Dimensions: Ensures interchangeability and compatibility with national pipe thread systems

Note:

Ensure compatibility with local codes and standards prior to installation. Always follow best practices when integrating cast iron components into mixed-material systems to avoid galvanic corrosion.

The 3/4" x 1/2" Galvanized Cast Iron Hex Bushing delivers dependable performance in demanding pipe systems. Its robust construction and standardized design make it a reliable solution for reducing NPT connections across various industrial and commercial environments.
