1/2 inch x 4 inch Chrome-Plated Brass Nipple

1/2" x 4" Lead-Free Brass Nipple for High-Performance Piping Systems

Designed for dependable service in potable water and hydraulic systems, the 1/2" x 4" Lead-Free Brass Nipple is a precision-machined fitting used to extend or connect threaded pipe sections. Its lead-free composition ensures compliance with federal and state potable water regulations, making it suitable for code-compliant installations.

Machined to exacting thread standards, this fitting supports consistent joint integrity and minimizes the potential for leakage under pressure. The brass construction offers superior resistance to corrosion and dezincification, which is critical in environments with variable water chemistry or temperature fluctuations.

Performance Features

• ✅ Lead-Free Alloy – Manufactured in accordance with lead content regulations for potable water systems.
• ✅ High-Precision Threads – Tapered NPT threads support secure engagement with other metallic fittings, reducing rework and joint failure.
• ✅ Thermal and Pressure Tolerance – Suitable for systems subject to elevated temperature and pressure cycles.
• ✅ Corrosion-Resistant Brass – Maintains structural integrity and performance across diverse piping environments.
• ✅ Streamlined Assembly – Designed for compatibility with standard sealants or Teflon tape for rapid installation and sealing.

Technical Specifications

• Material: Lead-free brass (meets NSF/ANSI 61-G and NSF/ANSI 372 requirements)
• Nominal Size: 1/2 inch NPT
• Length: 4 inches
• Thread Type: Male National Pipe Thread (NPT)
• Compliance: Certified for potable water use under applicable codes and standards

Applications

This fitting is commonly used in water distribution systems, hydronic heating loops, and mechanical piping assemblies. It is suitable for use in both new construction and retrofit projects where metal-to-metal connections are required without soldering.

Specification Note

To maintain code compliance, all components used in potable water systems must meet lead-free criteria as specified in the Safe Drinking Water Act. Threaded joints should be properly sealed and tested per local inspection guidelines.
