1/2 inch x 5-1/2 inch Brass Nipple

1/2" x 5-1/2" Red Brass Nipple – Machined for High-Integrity Connections

The 1/2" x 5-1/2" Red Brass Nipple is manufactured from lead-free alloy C69300 or equivalent, offering enhanced corrosion resistance and strength for potable water and mechanical piping systems. This fitting is designed for applications where dimensional consistency and long-term reliability are required under pressure and temperature fluctuations.

Performance and Construction Features

• Lead-Free Composition: Complies with Safe Drinking Water Act (SDWA) limits; certified for use in potable water systems in all U.S. jurisdictions.
• Corrosion Resistance: Suitable for aggressive water chemistries; resists dezincification, pitting, and scale formation in copper-alloy systems.
• Machined Threads: Threads conform to ANSI/ASME B1.20.1 for NPT engagement, ensuring a uniform, leak-resistant seal across both ends.
• High Pressure Compatibility: Rated for use in systems up to 200 PSI; suitable for both hot and cold water supply lines and heating circuits.

Dimensional and Technical Data

• Nominal Pipe Size: 1/2 inch
• Overall Length: 5-1/2 inches
• End Connections: Male NPT x Male NPT
• Material: Red Brass (typically UNS C69300 or C23000, depending on application)
• Certifications: NSF/ANSI 61 & 372, compliant with federal lead-free mandates

Installation Guidelines

Use PTFE thread seal tape or approved anaerobic thread compound when joining to female-threaded fittings. Avoid over-torquing to prevent thread distortion. Always verify alignment with local plumbing code requirements. This component is suited for solderless installation methods and is typically used in compression, threaded, or press-adapted assemblies.

Application Environments

Commonly used in both commercial and residential installations, including:

• Potable water distribution
• Boiler and hydronic heating circuits
• Chilled water return lines
• Transition connections in multi-metal systems

Compliance Advisory

All brass fittings used in drinking water systems must meet low-lead requirements under the Reduction of Lead in Drinking Water Act. This product conforms to the 0.25% weighted average lead content threshold.

The 1/2" x 5-1/2" Red Brass Nipple delivers mechanical strength, dimensional accuracy, and verified safety for pressure-rated plumbing systems. Its metallurgical integrity and corrosion resistance make it an optimal choice for demanding applications that require long-term service without degradation.
