3/4 inch x 3/8 inch Galvanized Cast Iron Bushing

3/4 inch x 3/8 inch Galvanized Malleable Iron Hex Bushing – Threaded Fitting for Pipe Size Reduction

The 3/4 inch x 3/8 inch Galvanized Malleable Iron Hex Bushing is designed to reduce pipe size in threaded plumbing systems while maintaining mechanical integrity and corrosion resistance. Manufactured to conform to industry standards, this fitting provides a durable solution for adapting connections between different nominal pipe diameters.

Product Specifications

• Type: Hex bushing – male to female pipe thread reducer
• Material: Galvanized malleable iron, ASTM A197
• Finish: Hot-dip zinc galvanized to ASTM A153
• Threading: ANSI B1.20.1 NPT (National Pipe Thread – Tapered)
• Size: 3/4 inch MIP x 3/8 inch FIP

Performance Characteristics

• Corrosion Protection: Galvanized finish provides resistance against moisture, condensation, and non-aggressive chemicals in air and water systems.
• Mechanical Strength: Designed for use in systems that require high durability under mechanical stress and variable temperatures.
• Thread Integrity: Precision-cut threads ensure a tight seal when used with approved pipe sealants.

Applications

Used primarily in low- to medium-pressure threaded piping systems for air, water, oil, or steam. Common in residential, light commercial, and mechanical system retrofits. Suitable for indoor or outdoor environments, provided exposure is within galvanizing limits.

Installation Notes

Ensure proper engagement of threads using compliant sealing materials such as pipe joint compound or PTFE tape. Do not over-torque to avoid thread deformation. For optimal system performance, match fitting with compatible materials and comply with local code requirements.

Standards Compliance

• Meets or exceeds ASTM and ANSI specifications for malleable iron fittings
• Lead-free compliant per NSF 372 (for non-potable systems unless otherwise certified)

The 3/4 inch x 3/8 inch Galvanized Malleable Iron Bushing is a robust solution for contractors requiring dependable thread transitions in steel or galvanized piping systems. Precision-machined and tested for dimensional accuracy, this component delivers consistent performance in field applications.
