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.
