1-1/2 inch x 1-1/4 inch Brass Hex Head Bushing Male x Female

1-1/2 inch x 1-1/4 inch Lead-Free Brass Hex Bushing – Threaded Reducer for System Integration

The 1-1/2 inch x 1-1/4 inch Brass Hex Bushing is a precision-machined fitting designed to reduce female pipe connections to smaller male-threaded diameters while maintaining structural integrity and system performance. Manufactured from lead-free brass, this hex bushing is ideal for potable water systems and meets federal low-lead compliance standards such as NSF/ANSI 372.

Engineered for commercial-grade reliability, this fitting features a hexagonal shoulder for easy installation with a wrench and durable NPT threads for consistent engagement and leak resistance. Its compact profile and corrosion-resistant construction make it a preferred choice in high-pressure and high-temperature environments where space and longevity are critical.

Performance Features

• ✅ Material: Lead-free brass, compliant with federal and state potable water codes
• ✅ Connection Type: Female NPT (1-1/2 inch) x Male NPT (1-1/4 inch)
• ✅ Thread Standard: ANSI/ASME B1.20.1 for compatibility with standard pipe fittings
• ✅ Hex Shoulder: Allows secure torque application using a wrench during installation
• ✅ Pressure Rating: Suitable for water, oil, gas (WOG) applications up to 1,200 PSI non-shock

Typical Applications

This hex bushing is used extensively in hydronic heating loops, potable water distribution systems, compressed air lines, and other industrial piping applications. It is particularly useful when reducing the pipe size in confined mechanical rooms or service areas where traditional reducers are too bulky.

Installation Guidance

For optimal sealing, apply PTFE tape or thread compound to the male threads prior to installation. Use a properly sized wrench on the hex shoulder to avoid over-torquing, which may compromise thread integrity. Always verify material compatibility with system media before assembly.

Code Compliance

This fitting meets the requirements for lead-free plumbing under the Safe Drinking Water Act and is suitable for use in systems requiring NSF 61 and NSF 372 certification.

Did You Know?

Hex bushings are often used in valve manifolds and control stations where multiple pipe sizes must be integrated into a single service block with minimal fittings and reduced leak paths.

The 1-1/2 inch x 1-1/4 inch Brass Hex Bushing offers the mechanical strength, corrosion resistance, and dimensional consistency required for high-performance installations. Whether integrating new infrastructure or performing retrofit work, this reducer delivers dependable service in demanding system configurations.
