2 inch x 4 inch Brass Nipple

2" x 4" Brass Pipe Nipple – Lead-Free, Threaded, Potable Water Rated

The 2" x 4" brass nipple is designed for threaded piping systems requiring a durable, corrosion-resistant transition between components. Manufactured from lead-free brass, this fitting supports potable water distribution and is also suitable for a range of mechanical and industrial fluid handling applications.

With male National Pipe Thread (NPT) ends, this Schedule 40 nipple ensures reliable engagement with female-threaded valves, couplings, or pipe sections. Precision machining provides uniform threading and minimizes the risk of joint failure under pressure or temperature fluctuations.

Product Specifications

• Size: 2" nominal pipe size x 4" length
• Material: Lead-free brass (compliant with NSF/ANSI 61 & 372)
• Connection Type: Male NPT x Male NPT
• Pressure Rating: Meets applicable pressure ratings for brass pipe under ASME B31.1 and B31.3
• Temperature Range: Up to 400°F depending on system pressure and media

Applications

This brass nipple is commonly used in:

• • Potable water service and distribution lines
• • Pump discharge and suction assemblies
• • Hot and cold water recirculation systems
• • Non-corrosive chemical and air line systems

Installation Notes

All threaded connections must be made using PTFE tape or thread sealant compound rated for the system’s media. Tighten with the appropriate tools without over-torquing to prevent thread damage. Ensure pipe alignment and support comply with mechanical code and job specifications.

Material Characteristics

Brass provides excellent corrosion resistance and machinability, especially in water systems. Lead-free brass compositions meet national plumbing regulations for safe use in potable water applications and are preferred in municipal, commercial, and industrial settings.
