1/2 inch x 3 inch Brass Nipple

1/2” x 3” Lead-Free Brass Nipple for Professional-Grade Plumbing Connections

The 1/2” x 3” Lead-Free Brass Nipple is a precision-machined component used to extend or connect pipe runs in residential and commercial systems. Fabricated from lead-free brass in accordance with ANSI and low-lead standards, this fitting is suitable for use in potable water and gas distribution applications.

Its compact profile and uniform threading make it an essential component for tight-space installations, transitions, or assemblies requiring exact spacing and alignment. Durable and corrosion-resistant, it offers reliability under varying temperature and pressure conditions.

Material and Performance Specifications

This nipple is machined from certified lead-free brass and finished to meet dimensional tolerances for compatibility with standard pipe threads. Key performance characteristics include:

• ✅ Uniform NPT Threading – Threads comply with ANSI B1.20.1 standards for tapered pipe threads, allowing for proper engagement and sealing.
• ✅ Lead-Free Compliance – Constructed from brass alloy containing ≤0.25% lead, meeting current federal Safe Drinking Water Act standards for potable water systems.
• ✅ Corrosion Resistance – Brass composition resists dezincification, scaling, and chemical breakdown in both water and gas environments.
• ✅ High Thermal Conductivity – Suitable for hot and cold water systems, capable of withstanding temperature fluctuations without structural degradation.
• ✅ High Pressure Tolerance – Rated for performance in systems up to standard PSI thresholds for water or air use, when properly installed with thread sealants.

Installation Recommendations

This fitting installs easily with standard tools and is compatible with brass, copper, CPVC, and other materials when using appropriate transition fittings. Apply Teflon® tape or thread compound to ensure a leak-tight seal. Thread engagement should be secure, avoiding overtightening to prevent thread damage.

Typical Applications

The 1/2” x 3” nipple is commonly used in:

• • Water supply systems (hot and cold)
• • Low-pressure gas lines
• • Hydronic heating circuits
• • Commercial plumbing manifolds and assemblies

Its short length and rigid construction make it ideal for joining fittings or valves in confined areas.

Code Compliance Note

Lead-free brass fittings are mandatory for potable water installations in jurisdictions governed by the U.S. Safe Drinking Water Act (SDWA) and similar regional codes. This product meets all applicable certifications for low-lead brass fittings.

Specify the 1/2” x 3” Lead-Free Brass Nipple when durability, precision, and compliance are required. Its material integrity and consistent machining support system longevity while minimizing the risk of failure or leakage over time.
