1/2 inch x 12 inch Chrome-Plated Brass Nipple

1/2" x 12" Lead-Free Brass Nipple – Threaded Extension for Potable and Mechanical Systems

The 1/2" x 12" Lead-Free Brass Nipple is a straight pipe fitting used to extend or connect threaded components in plumbing and mechanical systems. Fabricated from lead-free brass in accordance with NSF/ANSI 61 and 372 standards, this fitting is suitable for potable water, air, oil, and low-pressure gas lines. Threads are precision-cut to ANSI/ASME B1.20.1 standard to ensure proper mating with NPT fittings and valves.

Technical Features and Material Benefits

• ✅ Material: Lead-Free Brass (typically compliant with ASTM B584, C69300 or C46500)
• ✅ Connection Type: Male NPT x Male NPT
• ✅ Length: 12" overall with full-thread engagement on both ends
• ✅ Corrosion Resistance: Brass construction provides durability in potable and non-potable systems, especially where dissimilar metals are present
• ✅ Pressure Rating: Compatible with standard residential and light commercial pressure ranges (verify per system spec)

Applications

This fitting is widely used in water distribution systems, pump and boiler connections, valve assemblies, and gas piping networks. Its extended length makes it ideal for installations requiring offset spacing, horizontal transitions, or equipment stand-offs in mechanical rooms or utility enclosures.

Installation Notes

Use with approved thread sealants or PTFE tape to ensure a leak-resistant seal. Hand-tighten followed by appropriate torque with a pipe wrench—taking care not to damage threads. Avoid overtightening, especially when connecting to cast fittings or pressure-rated valves. Always install in accordance with applicable codes such as IPC, UPC, or local mechanical/plumbing regulations.

Material Compliance

Lead-free brass nipples are required for use in potable water systems under the U.S. Safe Drinking Water Act. These fittings support health and safety compliance while offering excellent tensile strength, thermal conductivity, and installation reliability.

The 1/2" x 12" Lead-Free Brass Nipple provides a long-lasting threaded solution for professional-grade installations where accuracy, corrosion resistance, and code compliance are critical. Trusted for use in both residential and commercial applications requiring extended nipple lengths.
