3/4 inch x 1/2 inch Brass Hex Head Bushing Male x Female

3/4 inch x 1/2 inch Lead-Free Brass Hex Bushing – NPT Threaded Reducing Fitting

The 3/4 inch x 1/2 inch Lead-Free Brass Hex Bushing is designed for reducing female-threaded openings to accept smaller male-threaded components in pressurized water and fluid systems. Machined from lead-free brass in compliance with federal Safe Drinking Water Act (SDWA) requirements, this fitting is suitable for potable water systems, as well as general plumbing and mechanical applications.

Hexagonal faces allow for precise tightening using standard wrenches. Threads are manufactured to ANSI/ASME B1.20.1 standards, ensuring compatibility and a secure seal with other NPT fittings. The bushing supports use in both residential and commercial environments where size transitions between threaded components are required.

Technical Specifications

• Material: Lead-free brass (≤0.25% lead content)
• Nominal Sizes: 3/4 inch male NPT x 1/2 inch female NPT
• Connection Type: Male x Female NPT, hex-head bushing
• Standards: ANSI/ASME B1.20.1 threads, NSF/ANSI 61 & 372 certified
• Temperature Rating: Up to 200°F (dependent on system requirements)
• Maximum Working Pressure: Up to 200 PSI (non-shock, water applications)

Installation Guidelines

Apply PTFE tape or a pipe joint compound to the male threads before insertion. Do not overtighten, as excessive torque may damage the fitting or mating components. Use a properly sized wrench on the hex portion to ensure even and controlled installation torque. Ensure system depressurization before maintenance or replacement.

Use Applications

Commonly used in potable water distribution systems, hydronic heating, irrigation networks, and industrial piping where a reduction in line size is required. This fitting is often installed at valves, manifolds, or equipment inlets to transition between larger piping and control devices or outlets.

Code Compliance

Lead-free brass bushings meet federal and state plumbing codes for use in drinking water systems. They are required in jurisdictions where NSF/ANSI 372 and 61 certifications are mandated for potable water components.

Code-Compliant Threaded Reducing Bushing for Potable and Non-Potable Systems

The 3/4 inch x 1/2 inch Lead-Free Brass Hex Bushing provides a durable, corrosion-resistant, and regulation-compliant solution for threaded size transitions. Its mechanical strength and standardized construction make it an ideal choice for professionals working on regulated plumbing and fluid handling systems.
