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

1/2" x 1-1/2" Lead-Free Brass Nipple – Threaded Fitting for Potable Water and General Piping Systems

The 1/2" x 1-1/2" Lead-Free Brass Nipple is machined from certified low-lead brass and threaded at both ends to ANSI B1.20.1 specifications. It is intended for use in potable water distribution systems, hydronic loops, and other general-purpose applications requiring corrosion-resistant, non-ferrous components.

Manufactured to meet lead content requirements in accordance with NSF/ANSI 61 and 372, this fitting is suitable for installations governed by the Safe Drinking Water Act. The brass alloy used offers high machinability, pressure tolerance, and resistance to dezincification, making it a durable choice for water, air, and low-pressure oil systems.

Key Technical Attributes

• Material: Lead-free brass compliant with NSF/ANSI 372 and federal potable water standards
• Size: 1/2" nominal pipe size x 1-1/2" overall length
• Thread Type: Male NPT on both ends (conforming to ANSI B1.20.1)
• Pressure Rating: Suitable for use in systems rated up to 200 PSI (non-shock water, oil, air)
• Temperature Range: Operates effectively from -20°F to 400°F, depending on media

Installation Considerations

Threaded installation requires compatible female NPT fittings. Use an appropriate thread sealant or PTFE tape approved for the system media. Avoid excessive torque to preserve thread integrity. Always verify material compatibility with the fluid being conveyed and perform pressure testing in accordance with applicable plumbing codes.

Application Scope

This lead-free brass nipple is typically used in potable water systems, hot and cold water supply lines, heating equipment connections, and general piping assemblies in both residential and commercial plumbing systems. It is ideal for corrosion-sensitive areas where ferrous materials are not permitted.

Material Insight

Lead-free brass components are mandated by federal law for use in drinking water applications. In addition to regulatory compliance, they provide excellent corrosion resistance, making them a preferred option for long-term performance in systems with aggressive water conditions.
