3/8 inch x 1/4 inch Brass Hex Head Bushing Male x Female

3/8 inch x 1/4 inch Lead-Free Brass Hex Bushing – Threaded Reducing Adapter for Potable Systems

The 3/8 inch x 1/4 inch Lead-Free Brass Hex Bushing is a precision-machined reducing fitting used to connect female-threaded pipe or fittings to a smaller male-threaded component. Designed for use in potable and non-potable systems, this hex bushing provides a corrosion-resistant and code-compliant solution for pressure and fluid distribution applications where size reduction is required.

Fabricated from lead-free brass that meets NSF/ANSI 61 and 372 requirements, the fitting is suitable for potable water systems under federal and state low-lead regulations. Its hex head profile allows for easy installation using standard wrenches, and the tapered NPT threads ensure a tight mechanical seal when installed with appropriate joint compounds or PTFE tape.

Key Technical Features

• ✅ Material: Lead-free brass, compliant with NSF/ANSI 61 and 372 for potable water applications.
• ✅ Connection Type: Male NPT x Female NPT – tapered threads ensure leak-resistant mechanical engagement.
• ✅ Hex Head Profile: Allows for precise torque application using open-end or adjustable wrenches.
• ✅ Size: 3/8 inch male x 1/4 inch female nominal pipe thread.
• ✅ Operating Pressure: Suitable for use in cold and hot water lines, HVAC systems, and compressed air setups within specified pressure limits.

Installation Guidelines

Apply thread sealant or PTFE tape to male threads before insertion. Hand-tighten initially, followed by wrench tightening to spec. Avoid overtightening to prevent thread distortion or cracking. Use in accordance with local plumbing codes and standards, particularly for potable water system connections.

Typical Applications

• Transitioning between different NPT pipe sizes in potable and non-potable water systems
• Used in backflow prevention assemblies, mixing valves, and pressure regulator inlets
• HVAC and hydronic system piping
• Compressed air and low-pressure fluid systems

Regulatory Note

Certified lead-free brass fittings are required in potable systems across all U.S. jurisdictions. Always verify that product grade and markings comply with applicable code prior to installation.
