2 inch x Close Brass Nipple

2" x Close Brass Nipple – Lead-Free Threaded Connector for Potable and General Service Lines

The 2" x Close brass nipple is a short-length, male-threaded fitting designed to provide a compact transition between female-threaded components in piping systems. Fabricated from lead-free brass, this component meets requirements for use in potable water applications and complies with federal and state low-lead regulations, including NSF/ANSI 61 and 372 certifications.

Its close design (threaded nearly end-to-end with minimal unthreaded length) allows for tight installations where space is constrained. Precision-cut NPT threads ensure proper sealing when installed with approved joint compounds or PTFE tape, supporting a leak-resistant joint under pressure.

Product Attributes and Advantages

• ✅ Material: Lead-free brass (compliant with ≤0.25% lead content regulations)
• ✅ Nominal Size: 2 inches
• ✅ Type: Close nipple (minimal exposed body between threads)
• ✅ Connection: Male NPT x Male NPT (per ANSI B1.20.1 threading standard)
• ✅ Corrosion Resistance: Suitable for use in potable water, air, and non-corrosive fluid systems

Installation Guidelines

Due to its short overall length, care must be taken when threading the close nipple to avoid over-tightening or misalignment. Use of non-hardening pipe sealant or approved PTFE tape is recommended to ensure a pressure-tight seal. Proper wrench engagement should be maintained to avoid damage to the fitting or mating component.

Common Applications

This fitting is frequently used in:

• Potable water supply systems
• Equipment connections in plumbing assemblies
• Water heater and manifold installations
• Branch line tie-ins for mixing valves and backflow preventers

Regulatory Note

Lead-free brass components are required for drinking water applications in accordance with the Safe Drinking Water Act (SDWA). The 2" x Close brass nipple is NSF 61/372 certified for contact with potable water and is suitable for installation in residential, commercial, and institutional systems.

The 2" x Close brass nipple offers a compact and code-compliant solution for short-span threaded connections where reliability and corrosion resistance are essential. Its lead-free composition and precise machining support long-term performance across a range of mechanical and water distribution applications.
