1-1/2 inch x 3 inch Brass Nipple

1-1/2" x 3" Lead-Free Brass Pipe Nipple – Machined for Performance and Durability

The 1-1/2" x 3" brass nipple is a precision-threaded fitting used to extend pipe runs or transition between components in plumbing and mechanical systems. Manufactured from lead-free brass, it provides dependable performance in potable water, air, and hydraulic applications requiring corrosion resistance and strength.

Key Features

• Material: Made from lead-free brass (≤0.25% lead content), suitable for potable water use in compliance with NSF/ANSI 61 and NSF/ANSI 372 standards.
• Connection Type: NPT male threads on both ends ensure a secure, leak-resistant seal with properly matched components.
• Dimensional Accuracy: Manufactured to industry-standard tolerances for precise mating with valves, couplings, or fittings.
• Corrosion Resistance: Brass provides excellent resistance to dezincification and stress cracking, extending system longevity in high-moisture or chemically active environments.
• High Pressure Compatibility: Withstands pressure ratings suitable for commercial water lines and general-purpose fluid transfer systems.

Specifications

• Nominal Size: 1-1/2 inch
• Length: 3 inches
• Material Standard: Brass, lead-free, ASTM B584 or equivalent
• Thread Standard: ANSI/ASME B1.20.1 NPT
• Certification: NSF certified for potable water system use

Installation Notes

• Use approved PTFE tape or compatible thread compound for sealing male threads.
• Ensure threads are fully engaged but not over-tightened to avoid distortion or galling.
• Confirm compatibility with system materials and pressure/temperature ratings prior to installation.

Application Areas

This brass nipple is frequently utilized in water heater connections, boiler systems, pump discharge lines, and general plumbing infrastructure. Its compact length and robust construction make it ideal for confined spaces or inline system connections where both strength and code compliance are critical.

Did You Know?

Lead-free brass fittings have been a requirement for drinking water systems under the federal Reduction of Lead in Drinking Water Act since 2014. Using certified fittings like this ensures compliance and protects end-user health and safety.

Whether you're completing a new build or updating an existing system, this 1-1/2" x 3" brass nipple provides professional-grade performance with long-term reliability. Engineered for demanding installations, it’s a trusted component in commercial and residential plumbing environments.
