1-1/4 inch x 1 inch Brass Hex Head Bushing Male x Female

1-1/4 inch x 1 inch Brass Hex Bushing – Lead-Free, Threaded Pipe Reducer

The 1-1/4 inch x 1 inch brass hex bushing is a threaded reducer fitting used to adapt larger female pipe openings to smaller male pipe sizes. Manufactured from lead-free brass, this component is suitable for use in potable water, compressed air, and mechanical systems requiring corrosion-resistant performance and dimensional stability.

Its hexagonal body simplifies torque application during installation, making it ideal for confined spaces and retrofit assemblies. Threads are machined to ANSI/ASME B1.20.1 standards to ensure consistent sealing performance in pressure-rated applications.

Key Features

• ✅ Lead-Free Brass Construction: Complies with federal and state regulations for use in potable water systems.
• ✅ Hex Body Profile: Allows for secure wrench grip during installation, especially in tight or recessed fittings.
• ✅ Thread Compatibility: Male and female NPT threads for seamless integration with standard pipe systems.
• ✅ Pressure Tolerance: Suitable for moderate pressure systems—verify rating per project specification.
• ✅ Corrosion Resistance: Brass resists dezincification and scaling, extending system service life.

Installation Guidelines

Apply PTFE tape or pipe joint compound to the male threads prior to installation. Wrench should be applied to the hex flats only to avoid over-stressing the body or thread ends. Always verify material compatibility with the pipe media and adhere to local plumbing codes.

Application Uses

This hex bushing is commonly specified in residential and commercial plumbing systems for transitioning between pipe sizes in water supply lines, valve assemblies, and pump systems. It is also used in irrigation, compressed air, and mechanical equipment where robust, compact reducers are required.

Material and Compliance Note

Lead-free brass formulations used in this fitting meet NSF/ANSI 61 and NSF/ANSI 372 requirements for low-lead content, making them compliant for use in drinking water installations under current federal guidelines.
