1/2 inch x 5 inch Brass Nipple

1/2" x 5" Lead-Free Brass Pipe Nipple – NPT Threaded Connector for Potable and Mechanical Systems

The 1/2" x 5" Lead-Free Brass Nipple is a straight, Schedule 40 pipe fitting with National Pipe Taper (NPT) male threads on both ends. It is used for extending pipe runs or joining two female-threaded components in pressurized water systems, HVAC installations, and various mechanical applications requiring corrosion resistance and code compliance for potable water use.

This fitting is machined from lead-free brass alloy (commonly C69300 or equivalent), conforming to federal low-lead mandates and certified under NSF/ANSI 61 and 372. It is compatible with copper, CPVC, or PEX transition assemblies and suitable for use in both hot and cold water systems.

Product Features

• ✅ Material: Lead-free brass, dezincification-resistant (DZR), compliant with ASTM B584 and ANSI/NSF standards.
• ✅ Connection: NPT male x NPT male, cut and gauged to ASME B1.20.1 specifications.
• ✅ Length: 5 inches overall, including thread engagement.
• ✅ Pressure Rating: Up to 200 PSI at 180°F depending on system configuration and sealing method.
• ✅ Application: Used in potable water supply lines, boiler hookups, water heaters, pump assemblies, and general plumbing systems.

Installation Considerations

Apply PTFE thread tape or a certified thread sealant to both ends before insertion into female-threaded fittings. Use appropriate torque to avoid over-tightening and potential thread damage. For compliance with plumbing codes, installation must be performed by qualified personnel using approved methods and materials.

Typical Use Cases

This fitting is suitable for residential, commercial, and light industrial systems requiring durable and corrosion-resistant pipe extensions. It is frequently used for faucet risers, valve transitions, manifold hookups, and equipment connections where brass is specified for its performance in water exposure conditions.

Code Compliance Note

Lead-free brass components used in drinking water applications must comply with the Safe Drinking Water Act, limiting lead content to no more than 0.25% across wetted surfaces. This nipple meets or exceeds the requirements of NSF/ANSI 61 and 372 for potable systems.
