1 inch x 3 inch Brass Nipple

1" x 3" Lead-Free Brass Pipe Nipple – Built for Pressure-Rated Plumbing Applications

The 1" x 3" Lead-Free Brass Pipe Nipple is a precision-machined fitting designed for joining two female-threaded components in potable water, hydraulic, or air systems. Manufactured from lead-free brass, it meets NSF 61 and NSF 372 standards, ensuring safety in drinking water applications and compliance with national plumbing codes.

Its high corrosion resistance and ability to withstand elevated temperatures and pressures make it suitable for both commercial and residential systems. The uniform threading and smooth surface finish contribute to leak-free installations and extended service life in demanding environments.

Key Advantages

• ✅ Lead-Free Compliance – Fabricated from dezincification-resistant, lead-free brass in accordance with federal Safe Drinking Water Act (SDWA) requirements.
• ✅ Threaded Ends – NPT (National Pipe Thread) male threads on both ends allow for secure mechanical connections in metal and polymer systems.
• ✅ Pressure-Tolerant – Suitable for use in systems operating at pressures up to 1,200 PSI (non-shock), depending on application and temperature.
• ✅ Corrosion Resistant – Excellent chemical resistance in potable water and low-salinity industrial environments.
• ✅ Temperature Range – Effective in fluid systems with temperatures up to 400°F, based on system design and compatibility.

Specifications

• Material: Lead-free brass (DZR-rated)
• Size: 1 inch nominal diameter x 3 inch length
