3/4 inch x 1/2 inch Black Iron Bushing

3/4 inch x 1/2 inch Black Malleable Iron Bushing – Threaded Reducing Fitting for Gas and Fluid Systems

The 3/4 inch x 1/2 inch Black Malleable Iron Bushing is designed for reducing pipe size within threaded systems, typically used in gas, air, water, and steam distribution lines. This fitting transitions between a 3/4-inch female threaded opening and a 1/2-inch male threaded connection, allowing for secure integration of differing pipe sizes while maintaining system integrity.

Manufactured from ASTM A197 malleable iron and finished with a black oxide coating, this reducing bushing provides durability and pressure resistance appropriate for use in non-corrosive environments. Threads are machined to ANSI B1.20.1 NPT standards, ensuring compatibility with standard North American pipe systems.

Performance Features

• ✅ ASTM A197 Construction – Malleable iron material supports mechanical strength in pressure-rated systems.
• ✅ Threaded NPT Design – Precision-cut threads provide reliable engagement with mating fittings, minimizing leak risk.
• ✅ Corrosion-Resistant Coating – Black finish helps protect against mild atmospheric corrosion in dry environments.
• ✅ Reduced Size Transition – Enables efficient connection between larger and smaller diameter piping components.
• ✅ Code-Compliant – Conforms to ASME B16.3 and B16.14 specifications for malleable iron fittings.

Installation Guidelines

This bushing is designed for threaded assemblies in rigid piping systems. Installation should be done using appropriate pipe wrenches and sealing compounds (such as PTFE tape or pipe dope) rated for the intended media. Avoid over-tightening to prevent thread damage. This product is not intended for use in potable water systems without certification to lead-free standards.
