3/4 inch x Close Brass Nipple

3/4" Brass Nipple – Lead-Free Threaded Connector for Potable and Non-Potable Systems

The 3/4" Brass Nipple is a precision-machined fitting designed for joining two female-threaded pipe components in residential, commercial, or industrial plumbing systems. It is commonly used in potable water service lines, heating system manifolds, and low-pressure fluid transfer assemblies requiring corrosion-resistant performance and code compliance.

Manufactured from lead-free brass in accordance with ANSI and ASTM standards, this nipple features male NPT (National Pipe Thread) threads on both ends and is rated for both above-ground and concealed piping installations. It provides dimensional consistency, mechanical strength, and safe use in potable water distribution as required by federal and local plumbing codes.

Installation Guidelines

Threaded brass fittings should be installed using PTFE tape or approved thread compound. Avoid overtightening to preserve thread form and prevent cracking. Installation should follow applicable codes such as IPC, UPC, and ASME B31 for mechanical and potable water systems.

Typical Applications

This 3/4" brass nipple is commonly used in water heater connections, boiler loop piping, recirculation lines, and fixture riser terminations. It is compatible with copper, CPVC, PEX transition fittings, and other approved materials where threaded male connections are specified.

Material Advisory

Brass fittings offer natural antimicrobial resistance and long-term dimensional stability, making them suitable for both cold and hot water supply systems in code-regulated environments.

The 3/4" Brass Nipple is engineered for performance, safety, and compliance across a range of plumbing and mechanical system designs requiring durable and corrosion-resistant threaded connections.
