1/2 inch x Close Brass Nipple

1/2” x Close Brass Pipe Nipple – Machined for High-Integrity Connections

The 1/2” x Close Brass Pipe Nipple is precision-machined to provide a reliable threaded connection between fittings or pipe segments in pressurized plumbing systems. Manufactured from lead-free brass, this component offers corrosion resistance and mechanical strength, supporting long-term service in potable water, air, or oil distribution systems.

Close nipples are designed with minimal length between threads, enabling compact installations where space is limited. Threads are cut to NPT standards, ensuring compatibility with other threaded brass, copper, or galvanized steel components in accordance with plumbing codes.

Performance Features

• ✅ Material: Lead-free brass for corrosion resistance and potable water compliance
• ✅ Size: 1/2” nominal pipe size
• ✅ Length: Close (no unthreaded section between male threads)
• ✅ Thread Type: NPT (National Pipe Tapered) male threads on both ends
• ✅ Standards: Complies with ANSI B1.20.1 thread specifications and lead-free plumbing mandates (NSF/ANSI 61, NSF/ANSI 372)

Typical Applications

This brass nipple is commonly used to join valves, tees, elbows, and other threaded components in:

• Potable water supply systems
• Compressed air lines
• Low-pressure gas distribution (where approved)
• Hydronic heating systems

Installation Considerations

Apply PTFE thread sealant tape or pipe joint compound to ensure leak-tight connections. Due to its close length, proper alignment during threading is critical to avoid over-torque or damage to mating components. Use of compatible tools to maintain concentric thread engagement is recommended. Always pressure test assemblies per local code requirements before final use.

Note on Material Compliance

Brass nipples produced from lead-free alloys help meet requirements under the Safe Drinking Water Act (SDWA) for use in potable systems. The product is labeled accordingly for inspection and certification.

The 1/2” x Close Brass Pipe Nipple is a critical fitting for tight-space transitions where mechanical durability and code compliance are essential. Suitable for both new installations and repairs in regulated systems.
