1-1/4 inch x 2-1/2 inch Brass Nipple

Brass Pipe Nipple – 1-1/4" x 2-1/2", Lead-Free, Threaded MIP x MIP

The 1-1/4" x 2-1/2" Brass Pipe Nipple is a straight-threaded fitting used to connect female-threaded components in potable water, compressed air, and non-corrosive fluid systems. Manufactured from lead-free brass, this nipple is designed for use in applications requiring mechanical strength, corrosion resistance, and compliance with drinking water standards.

This fitting features male National Pipe Tapered (NPT) threads on both ends and is machined to ANSI/ASME B1.20.1 specifications. It is suitable for use in residential, commercial, and industrial systems where temperature and pressure demands fall within the limits of brass pipe standards.

Product Features

• ✅ Connection Type: MIP x MIP (Male Iron Pipe Threads)
• ✅ Size: Nominal 1-1/4" diameter, 2-1/2" overall length
• ✅ Material: Lead-free brass (≤0.25% lead content), compliant with NSF/ANSI 61 and 372
• ✅ Pressure Rating: Suitable for use up to 200 PSI in typical water supply systems
• ✅ Corrosion Resistance: Brass construction resists dezincification and is non-reactive to potable water chemistry

Installation Guidelines

Apply PTFE tape or approved pipe joint compound to male threads before assembly. Use a wrench to tighten, gripping the flats or external surface to avoid thread damage. Avoid over-tightening to maintain thread integrity and prevent cracking in mating components. Always follow local code requirements for threaded brass fittings.

Typical Applications

Commonly used in water distribution systems, water heaters, irrigation valves, and equipment connections, this brass nipple is ideal for joining two female-threaded fittings or extending threaded pipe runs. It is suitable for both hot and cold water lines and can be used in systems requiring lead-free components.

Compliance Note

This fitting meets the requirements of the Safe Drinking Water Act (SDWA) and is certified for potable water use under NSF/ANSI 61 and NSF/ANSI 372. It may be installed in any jurisdiction where lead-free components are mandated for plumbing systems.
